(S) -1 - (2,6 - difluoro - 3 - methoxyphenyl) ethanol, its physical properties are critical and related to many uses. The appearance of this substance is often a colorless to light yellow transparent liquid, like the shimmer through the mist in the morning, pure and clear. Under normal temperature and pressure, it is like a calm person, with relatively stable properties, and is not prone to sudden changes due to slight external interference. Looking at its melting point, it is about a certain low temperature range, like the quiet cold of a winter night. Although it cools orderly, the substance can gradually condense from a flowing state to a solid state at this temperature limit, and the change of shape also reflects the adjustment of its internal molecular arrangement. The boiling point is at a relatively high temperature, just like the fire is booming, and the molecules can break free from each other and jump from the liquid state to the gaseous state, starting a new state journey. In terms of solubility, in common organic solvents, it is like a fish entering a shallow abyss, and it has a certain solubility. In alcohol solvents, such as ethanol, it can be well soluble in each other, and the two blend together like old friends, regardless of each other; in ether solvents such as ether, it can also show certain solubility characteristics, but the degree may vary, as if different friends are close and distant. However, in water, the solubility is not good, just like the barrier between oil and water, and it is difficult to blend. This is due to the weak hydrophilicity of its molecular structure. The density of is similar to its internal "weight heritage". Under certain conditions, it has a fixed value, giving it a unique settling or floating characteristic in the mixture, just like finding its own position in the world, not floating or impatient. Refractive index is also one of its significant physical properties. When light passes through this substance, the path of light is like the steps of a dancer, bending according to specific laws, reflecting the unique "rhythm" of its internal structure, providing an important optical basis for identifying this substance, just like the unique temperament of a human being, which is difficult to confuse.

To prepare (S) -1- (2,6-difluoro-3-methoxyphenyl) ethanol, the method is as follows: First take 2,6-difluoro-3-methoxybenzaldehyde and dissolve it in a suitable solvent, such as tetrahydrofuran. Another Grignard reagent is prepared from magnesium and halogenated hydrocarbons, such as bromoethane. In a low temperature and nitrogen protected environment, the Grignard reagent is slowly dripped into a solution containing 2,6-difluoro-3-methoxybenzaldehyde. This process needs to be carefully controlled to ensure a smooth reaction. After dripping, the reaction continues for a period of time until the reaction is sufficient. After the reaction is completed, quench the reaction with a dilute acid solution, such as dilute hydrochloric acid. Then separate and purify, first extract with an organic solvent, such as ethyl acetate, and collect the organic phase. The organic phase is then dried with anhydrous sodium sulfate to remove its moisture. After that, it is distilled under reduced pressure to remove its solvent to obtain a crude product. The crude product is purified by column chromatography, and an appropriate eluent is selected, such as the mixture of petroleum ether and ethyl acetate. The ratio needs to be adjusted according to the experimental conditions. After this step, pure (S) -1- (2,6-difluoro-3-methoxyphenyl) ethanol can be obtained. This synthesis method requires fine operation in each step, and the conditions must be precisely controlled to achieve good results.

I have not heard of (S) -1- (2,6-difluoro-3-chlorophenyl) ethanol in the market price range. This substance is not a common substance in my time, and no relevant price records have been found in the classics I know. In today's world, the price of all things often changes with time, varies with the supply and demand of the market, and the price varies from place to place. Or this substance is a new chemical substance, and its price may be affected by many factors. The cost of production, such as the price of raw materials and the difficulty of production, all affect its price. And if it is widely used, and those who need it are many, the price may be high; if the use is limited and those who need it are few, the price may be low. However, it is difficult for me to determine the price range. If you want to know the details, you can ask people who are proficient in chemical trade today, or look up the books and information of current chemical transactions, in order to obtain a more accurate price range.

(S) - 1 - (2,6 -difluoro-3 -methoxyphenyl) ethanol is an organic compound, and its storage conditions are very critical. This compound should be placed in a cool, dry and well-ventilated place. Because of the cool environment, it can slow down its chemical reaction rate and prevent it from deteriorating due to excessive temperature; dry place, it can avoid moisture, avoid structural changes or other adverse reactions caused by moisture intervention; well-ventilated, it can disperse harmful gases that may be generated in time to maintain its chemical stability. and must be kept away from fire and heat sources. Fire and heat sources are prone to sudden temperature rise, or lead to combustion, explosion and other hazards, endangering storage safety. At the same time, it should be stored separately from oxidants, acids, bases, etc., and must not be mixed. The edge oxidant has strong oxidizing properties, and the chemical properties of acids and bases are active. Coexistence with the compound can easily induce chemical reactions, damage its quality, and even lead to safety accidents. When storing, also pay attention to the integrity of the package. If the package is damaged, external air, moisture and other impurities can easily invade, affecting the purity and stability of the compound. The stored (S) -1- (2,6-difluoro-3-methoxyphenyl) ethanol should be inspected regularly to see if its appearance and condition are abnormal, so as to detect problems in time and dispose of them properly to ensure the quality and safety during storage.
