Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its functional groups enable coupling reactions and heterocycle formation, making it valuable in constructing bioactive molecules. Commonly employed in the preparation of aromatic amides and nitrogen-containing ring systems, it supports the creation of compounds with potential antimicrobial or anti-inflammatory activity. Also utilized in research settings for derivatization and labeling due to its reactivity with amines and alcohols under mild conditions.
