This compound is a valuable disubstituted aminobenzoate fine chemical intermediate, containing amino, methyl and ethyl ester groups on the benzene ring. Multiple functional groups support diversified synthetic derivatization: amino group for acylation, diazotization and condensation reactions; methyl group for oxidation and substitution; ethyl ester group for hydrolysis, amidation and reduction modification. It is widely used as a core building block in the synthesis of anti-inflammatory, analgesic, antibacterial and antitumor pharmaceutical intermediates. It also applies to organic synthetic route development, heterocyclic compound construction, pesticide raw materials, cosmetic functional additives and chromatographic reference standards, occupying an important position in pharmaceutical chemical and fine chemical industry.

This aromatic amino ester compound has mild skin and eye irritation risks. Direct skin contact may cause redness, dryness and slight itching discomfort, especially for sensitive skin. Eye contact will lead to stinging, tearing and conjunctival congestion, which should be immediately rinsed with plenty of clean water. Inhalation of fine dust or volatile vapor may irritate respiratory mucosa, causing throat dryness and mild cough. Accidental ingestion may induce slight gastrointestinal nausea and abdominal distension. When handling, wear chemical-resistant gloves, protective goggles and dust mask, and operate in a well-ventilated fume hood. Store in tightly sealed, dry, cool and dark environment, away from strong oxidants, strong acids and heat sources. Waste residues and contaminated packaging must be treated as hazardous waste, and arbitrary discharge into water and soil is strictly prohibited.
