Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antimicrobial agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating compounds with targeted biological activity. It is also employed in agrochemical research for designing herbicides and plant growth regulators due to its ability to interact with specific enzyme systems in pests and weeds. The carboxylic acid group facilitates coupling reactions, enabling the construction of complex molecules in drug discovery and crop protection chemistry.
