Used in the synthesis of pharmaceutical intermediates, particularly in the development of nonsteroidal anti-inflammatory drugs (NSAIDs). It serves as a building block for active pharmaceutical ingredients due to its amine and carboxylic acid functional groups, which allow for easy modification and coupling reactions. Also employed in the preparation of dyes and pigments, where its aromatic structure contributes to color stability and intensity. Its derivatives are explored in agrochemicals for crop protection agents owing to their structural specificity and reactivity.
