This compound is a valuable substituted aminobenzoate intermediate containing amino and ethyl ester groups on the benzene ring. It is widely applied in pharmaceutical synthesis, fine chemical derivatization, pesticide and organic material research. The amino group can undergo diazotization, acylation and condensation reactions, while the ethyl ester group supports hydrolysis, amidation and reduction modification. It acts as a key building block for the synthesis of anti-inflammatory, analgesic, antibacterial and antitumor drug intermediates, as well as heterocyclic compound frameworks. It is also commonly used in the preparation of organic synthetic raw materials, chiral ligands, cosmetic functional additives and chromatographic reference standards, playing an important role in laboratory process development and industrial fine chemical production.

This substance is an aromatic amino ester with mild irritant characteristics. Direct skin contact may cause redness, dryness and slight allergic itching, especially for sensitive skin. Eye contact will lead to stinging, tearing and conjunctival irritation, requiring immediate rinsing with plenty of clean water. Inhalation of volatile vapor may irritate respiratory mucosa, causing throat dryness and cough discomfort. Accidental ingestion may induce mild gastrointestinal nausea and abdominal distension. During handling, wear chemical-resistant gloves, safety goggles and organic vapor mask, and operate in a well-ventilated fume hood. Store in sealed, dry, cool and dark place, away from strong oxidants, strong acids and heat sources. Waste liquid and residues must be disposed of strictly per hazardous waste regulations, prohibiting arbitrary discharge to avoid water and soil environmental pollution.
