Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of isonicotinic acid derivatives with biological activity. It serves in the preparation of compounds targeting central nervous system disorders, inflammatory conditions, and antimicrobial agents such as antitubercular drugs. Its bromo and carboxylic acid functional groups allow for selective cross-coupling reactions and derivatization, making it valuable in medicinal chemistry and drug discovery. Also employed in agrochemical research for designing novel pesticides and herbicides due to its structural specificity and reactivity.
