3-Amino-2-chloropyridine is a vital disubstituted pyridine heterocyclic intermediate containing amino and chloro functional groups with high chemical reactivity. It can efficiently participate in nucleophilic substitution, acylation, cyclization and coupling reactions to construct diversified pyridine-based molecular skeletons. It is mainly applied in pharmaceutical industry for the synthesis of anti-inflammatory drugs, antibacterial agents, antiviral medicines and central nervous system therapeutic agents, and serves as core building block for developing targeted therapeutic drugs and anti-tumor intermediates. In agrochemical field, it is widely used to synthesize high-efficiency fungicides, insecticides and herbicides, which can effectively improve biological activity and reduce drug resistance. Besides, it is used for manufacturing dye intermediates, organic catalysts and chemical analytical reagents. It also acts as an essential raw material for new material additives and fine chemical derivatives synthesis. With stable molecular structure and excellent reaction versatility, this intermediate is widely adopted in pharmaceutical research, pesticide production and organic synthesis fields, possessing great research value and stable market application prospect in global fine chemical industry.

This chemical belongs to moderate irritant substance with certain health risks during handling. Inhalation of fine dust will cause obvious irritation to respiratory tract, easily triggering sore throat, cough and chest discomfort, so operators must wear dust-proof mask and keep working environment fully ventilated. Direct skin contact may lead to local redness, itching and allergic irritation, staff need to wear nitrile protective gloves and protective garments, and thoroughly clean contacted skin with soap and running water after operation. Once the powder splashes into eyes, it will cause severe stinging and conjunctival inflammation, immediately flush eyes with plenty of flowing clean water for more than fifteen minutes and seek professional medical treatment in time. Accidental ingestion will induce nausea, abdominal pain and other gastrointestinal symptoms, do not induce vomiting blindly and receive timely medical treatment. It is stable at normal temperature, but easy to be oxidized and deteriorated under strong light and humid conditions, and incompatible with strong oxidants and strong acids. Keep sealed away from heat sources during storage. All waste materials shall be disposed strictly in accordance with local hazardous waste regulations to avoid personal injury and environmental pollution.
