Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the production of pyrazoles and other nitrogen-containing rings. Commonly applied in pharmaceutical manufacturing for building active pharmaceutical ingredients (APIs), especially in antipyretic and analgesic drug classes. Also utilized in agrochemical synthesis for developing herbicides and plant growth regulators. Its bifunctional nature—bearing both amino and ester groups—makes it valuable in condensation reactions and peptide-like chain extensions in organic chemistry.
