Widely used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs) and antihypertensive agents. Its structure supports the formation of heterocyclic compounds, making it valuable in creating thienopyridines and other fused-ring systems with biological activity. It is also employed in agrochemical synthesis, contributing to the production of herbicides and plant growth regulators. Due to the presence of both amino and ester functional groups, it readily participates in condensation and cyclization reactions, enabling efficient construction of complex molecules in medicinal chemistry research.
