2-Chloro-3,4-dihydroxybenzoic acid(CAS: 87932-50-1)

2-Chloro-3,4-dihydroxybenzoic acid is a crystalline solid with a molecular weight of approximately 219.59 g/mol. It has a melting point of 224-227°C and a solubility in water of about 0.12 g/100 mL at 25°C. It is reactive towards bases and can undergo substitution and condensation reactions.

2-Chloro-3,4-dihydroxybenzoic acid is typically synthesized by chlorination of 3,4-dihydroxybenzoic acid using thionyl chloride as a reagent. The reaction is carried out under anhydrous conditions to avoid hydrolysis and dehydration reactions.

2-Chloro-3,4-dihydroxybenzoic acid is used in the pharmaceutical industry as an intermediate in the synthesis of certain drugs. It also finds applications in the polymer industry as a monomer for specific polymer formulations, and in the sensor industry for its chemical sensing capabilities.

When handling 2-Chloro-3,4-dihydroxybenzoic acid, appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. It should be stored in a cool, dry, and well-ventilated area. In case of spill, it should be handled with care, and appropriate spill kits should be used. Always consult the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
