As a leading Phenylmethylsulfonyl Fluoride supplier, we deliver high-quality products across diverse grades to meet evolving needs, empowering global customers with safe, efficient, and compliant chemical solutions.

What are the main uses of Phenylmethylsulfonyl Fluoride?

Phenylmethylsulfonyl fluoride (Phenylmethylsulfonyl Fluoride, PMSF) is an important reagent in biochemical research, and its main uses are as follows.
First, it is used to inhibit serine protease. Many serine proteases, such as trypsin, trypsin, elastase, etc., play a key role in the proteolysis process in vivo. PMSF can covalently bind to the serine residues in the active centers of these proteases to inactivate the enzyme, thereby inhibiting the proteolysis reaction. This is of great significance in studying the mechanism of proteolysis and preventing the protein from being over-degraded during the experimental process. For example, when extracting certain protease-sensitive proteins, the addition of PMSF can effectively protect the integrity of the target protein.
Second, it is widely used in cell lysis and protein extraction steps. During cell lysis, the proteases in the cell will be released, and if not inhibited, it will cause damage to the target protein. PMSF can quickly interact with these proteases to ensure that the extracted proteins maintain their natural structure and function, and help to obtain high-quality protein samples for subsequent experiments such as protein purification, structural analysis, and activity determination.
Third, it is also indispensable in the study of enzyme kinetics. By using PMSF to inhibit specific proteases, researchers can accurately observe the changes in enzymatic reactions, and in-depth explore the mechanism of action of enzymes, substrate specificity and other important parameters, providing key clues for understanding the complex enzymatic reaction network in organisms.
Fourth, PMSF is also used to protect proteins in biological samples from endogenous protease degradation. Whether it is tissue homogenate, cell culture supernatant, or other biological samples, as long as there is a potential threat to protease, PMSF can exert its effect of inhibiting protease activity, maintaining protein stability, and ensuring the accuracy and reliability of experimental results.

Phenylmethylsulfonyl how to use Fluoride

Phenylmethylsulfonyl Fluoride, that is, phenylmethylsulfonyl fluoride, referred to as PMSF, is a reagent that has a strong inhibitory effect on serine protease and cysteine protease. Its use method is as follows:
In biochemical experiments, PMSF is often dissolved in anhydrous ethanol, isopropanol, DMSO and other organic solvents. Because PMSF is extremely unstable in aqueous solution and will degrade in about half an hour, it should be prepared fresh when used.
Generally speaking, its working concentration is mostly 0.1 to 1 mmol per liter. For example, when extracting proteins, in order to inhibit protease activity and prevent protein degradation, PMSF can be added to cell lysate. The specific operation is to prepare PMSF into a high-concentration mother liquor, such as 100 mmol per liter, and add the lysate in an appropriate proportion before use.
When handling samples, be sure to pay attention to the fact that PMSF is highly toxic and highly irritating to the eyes, respiratory mucosa, and skin. Wear appropriate protective equipment during operation, such as gloves, goggles, and masks. And after the experiment, the waste containing PMSF needs to be properly disposed of to prevent environmental pollution.
In short, when using PMSF, it is necessary to strictly follow the experimental requirements and safety procedures, and precisely control the concentration and treatment time, so as to achieve the purpose of inhibiting protease while ensuring the safety of the experimental personnel and the experimental environment is not endangered.

What are the precautions for Phenylmethylsulfonyl Fluoride?

Phenylmethylsulfonyl Fluoride (PMSF) is a commonly used reagent in biochemical experiments, and many matters need to be paid attention to when using it.
First, this reagent is highly toxic and highly irritating, and can be life-threatening when it comes into contact with the skin, inhaled or eaten by mistake. Therefore, when using it, be sure to be fully armed, wearing laboratory clothes, gloves and goggles, and operate in a fume hood to prevent inadvertent contact.
Second, PMSF is unstable in nature and prone to hydrolysis failure. Therefore, anhydrous organic solvents, such as isopropyl alcohol, ethanol, etc., should be used to prepare the solution, and it should not be left for a long time.
Third, after using PMSF to treat the sample, follow-up operations should also be cautious. Because it can inhibit a variety of proteases, or affect the follow-up experiment, it needs to be properly handled to remove the residual reagents and avoid interfering with the experimental results.
Fourth, after the experiment is completed, the waste containing PMSF needs to be properly disposed of. It should not be dumped at will, but should be stored in a specific container and treated harmlessly in accordance with relevant regulations to prevent environmental pollution.
In short, when using Phenylmethylsulfonyl Fluoride, it should be treated strictly from the operating specifications to the waste treatment to ensure the safety of the experiment and the accuracy of the results.

What are the storage conditions for Phenylmethylsulfonyl Fluoride?

Phenylmethylsulfonyl fluoride (Phenylmethylsulfonyl Fluoride, referred to as PMSF) is a highly toxic reagent, and it should be stored with extreme caution.
First, it should be stored in a low temperature place. Because it is easy to decompose when heated, the activity is reduced, so it needs to be stored in the refrigerator, and the temperature should be controlled at -20 ° C. This low temperature environment can ensure the stability of its chemical properties and delay the rate of decomposition.
Second, it needs to be placed in a dry place. PMSF is very easy to absorb moisture, and it is easy to hydrolyze and fail after moisture absorption. Therefore, it should be stored in a dryer, or a desiccant should be added to prevent the intrusion of moisture and ensure that it is dry and moisture-free.
Third, pay attention to sealed storage. PMSF is very volatile. If the seal is not good, it is easy to evaporate and dissipate, and the volatile gaseous substances are quite toxic, which endangers the environment and human body. Use a well-sealed container, and seal it immediately after taking it to prevent it from escaping.
Fourth, avoid light. Light can accelerate the decomposition of PMSF, so it should be stored in a brown bottle or in a dark place away from light to reduce the impact of light on it.
Fifth, store it separately. Because of its severe toxicity, it cannot be mixed with other reagents to prevent interaction, and it is easy to manage and access, reducing risks.
When storing PMSF, strictly observe the above conditions to maintain its activity and stability, and at the same time ensure the safety of the storage environment to avoid accidents.

What are the chemical properties of Phenylmethylsulfonyl Fluoride?

Phenylmethylsulfonyl fluoride, an organic compound, is widely used in the field of biochemical research. Its chemical properties are specific and have multiple key characteristics.
The first to bear the brunt, phenylmethylsulfonyl fluoride is a strong nucleophilic reagent. This property stems from its molecular structure. The activity of sulfonyl fluoride groups is extremely high, and fluorine atoms have strong electronegativity, which reduces the electron cloud density of sulfur atoms and makes them highly vulnerable to nucleophilic reagents. In many chemical reactions, it can react rapidly with molecules containing hydroxyl groups, amino groups and other nucleophilic groups to form stable covalent bonds.
Furthermore, this substance has a strong inhibitory effect on serine protease. The active center of serine protease contains serine residues, and its hydroxyl groups are nucleophilic. Phenylmethylsulfonyl fluoride can covalently bind to serine hydroxyl groups, thereby irreversibly inhibiting enzyme activity. This property makes it an important tool for studying the function and mechanism of serine protease, and is used in pharmaceutical research and development to explore therapeutic targets for related diseases.
In addition, the chemical properties of phenylmethylsulfonyl fluoride are relatively stable. Under conventional conditions, it can be stored for a long time without significant decomposition. When exposed to extreme conditions such as strong alkali and high temperature, its structure will be damaged. It has good solubility in organic solvents, such as common ethanol and acetone, which helps it to disperse uniformly in experimental operations and participate in various reactions. Phenylmethylsulfonyl fluoride plays a key role in many fields such as biochemistry and medicine due to its unique chemical properties, promoting the continuous development and progress of related disciplines.
