This compound is a key difunctional substituted benzoate intermediate with amino and bromine groups on the benzene ring. It features multiple reactive sites for diversified organic derivatization: the amino group can undergo acylation, diazotization and cyclization reactions; the bromine atom is suitable for Suzuki, Heck and other cross-coupling reactions; the methyl ester group can be hydrolyzed, amidated and reduced. It is widely used as an important building block in the synthesis of antitumor, anti-inflammatory, antibacterial and central nervous system drug intermediates. It is also applied in the preparation of heterocyclic compounds, organic optoelectronic materials, chiral ligands and fine chemical derivatives, commonly used in laboratory synthetic route design and industrial process optimization.

This aromatic bromo-amino ester is a mild irritant chemical. Direct skin contact may cause redness, dryness and slight allergic itching, especially for sensitive skin groups. Eye contact will lead to obvious stinging, tearing and conjunctival irritation, requiring immediate flushing with plenty of clean water. Inhalation of fine crystalline powder 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 dust mask, and operate in a well-ventilated fume hood. Store in tightly sealed, dry, cool and dark place, keep away from strong oxidants, strong acids and heat sources. Waste residues and contaminated packaging must be disposed of in accordance with hazardous chemical regulations, and arbitrary discharge into water and soil is prohibited.
