16273-37-3 - Introduction
Nature:
-Appearance: 3-Chloromandelic acid is a white crystalline solid.
-Solubility: The solubility in water is small, and the solubility in organic solvents (such as alcohol, ether) is high.
-Chemical properties: 3-chroomandelic acid is acidic and can react with alkali to generate the corresponding salt.
Use:
-3-choromandelic acid is often used in organic synthesis as an important intermediate.
-In drug manufacturing, it can be used to synthesize antibiotics, ester drugs and other organic compounds.
-In the dye industry, 3-chroomandelic acid can be used for the synthesis of dyes and the production of coating materials.
-In the cosmetics industry, it can be used as a preservative and acid regulator.
Method:
- 3-Chloromandelic acid can be obtained by reacting p-chlorobenzoic anhydride with sodium chloride. First, P-chlorobenzoic anhydride reacts with sodium chloride in an alcohol solvent to produce sodium 3-Chloromandelic acid, which is then treated with acid to obtain 3-Chloromandelic acid.
Safety Information:
-3-choromandelic acid is a relatively safe chemical substance under normal conditions, but the following matters still need to be paid attention:
-Avoid contact with skin and eyes as it may cause irritation and burns.
-use to maintain good ventilation.
-Avoid inhaling dust or gas to avoid breathing discomfort.
-Store in a cool, dry place, away from fire and oxidizing agents.
-Follow proper safety procedures when using and handling. In case of accident or discomfort, seek medical attention immediately.
