4-Amino-2-chlorobenzoic acid is an important fine chemical intermediate with amino, chloro and carboxyl functional groups on benzene ring, possessing excellent chemical reaction activity. It is widely used in pharmaceutical synthesis field, mainly applied to prepare anti-inflammatory drugs, antibacterial medicines, analgesics and various targeted therapeutic drug intermediates. It can carry out diazotization, acylation, esterification, reduction and coupling reactions to construct diversified aromatic compound structures. In pesticide industry, it is used for synthesizing high-efficiency herbicides, fungicides and insecticides with stable biological activity. Besides, it is commonly used as raw material for organic dyes, pigment additives and chemical analytical reagents. With stable molecular structure and easy derivatization, this product is widely adopted in laboratory research, pilot test and industrial mass production, occupying an essential position in the production chain of medical and pesticide fine intermediates.

This chemical belongs to common irritating raw material with certain health risks during operation. Inhalation of fine dust will cause obvious irritation to respiratory tract, easily lead to throat pain, cough and chest discomfort, so operators need to wear dust-proof mask and keep working environment fully ventilated. Direct skin contact will cause local redness, itching and mild allergic inflammation, staff must wear chemical resistant gloves and clean the contacted skin with running water in time after work. Once the powder accidentally enters eyes, it will produce severe stinging pain and conjunctival swelling, immediately flush eyes with plenty of flowing clean water for more than fifteen minutes and receive professional medical treatment without delay. Accidental oral intake will induce nausea, stomachache and other gastrointestinal adverse reactions, do not take food casually and drink sufficient warm water for relief. The product will release toxic nitrogen oxide and chloride harmful gas under high temperature decomposition. Keep it stored away from food, daily necessities and incompatible chemical substances. All waste residues shall be treated strictly in accordance with hazardous chemical disposal standards to effectively avoid personal injury and environmental pollution risks.
