2-Aminoquinoline is an important aromatic nitrogen heterocyclic intermediate with high chemical reactivity. It contains active amino group on quinoline ring, which can undergo diazotization, condensation, coupling and cyclization reactions to construct various quinoline derivative skeletons. It is widely used as core raw material for synthesizing anti-inflammatory, antibacterial, antiviral and anti-tumor pharmaceutical intermediates. It also serves as key building block for developing new veterinary drugs, pesticide fungicides and plant growth regulators. In chemical analysis field, it can be used as organic analytical reagent and metal ion chelating agent. Besides, it is frequently applied in custom fine chemical synthesis, dye intermediate preparation and organic synthetic methodology research, occupying an important position in pharmaceutical and fine chemical industrial chain.

This quinoline compound has moderate toxicity and obvious irritation to human body. Inhalation of fine crystalline dust will irritate respiratory mucosa, cause sore throat, dry cough and chest discomfort, and long-term inhalation may damage respiratory health. Skin contact is easy to cause local redness, itching and mild allergic inflammation, repeated contact will make skin dry and fragile. Direct eye contact will lead to severe stinging pain and conjunctival congestion, users need to rinse eyes continuously with plenty of clean water for more than fifteen minutes in time. Accidental ingestion will induce nausea, vomiting, abdominal distension and other gastrointestinal adverse reactions, excessive intake may affect internal organ functions. All operating work shall be completed in well-ventilated fume hood, and workers must wear dust-proof mask, chemical resistant gloves and safety goggles. Keep products sealed and stored separately from food and daily supplies. Waste residues and contaminated packaging shall be disposed strictly in accordance with local hazardous waste rules to prevent environmental pollution and hidden safety hazards.
