Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of analgesic and anti-inflammatory drugs. It serves as a building block in organic synthesis due to the presence of both amino and carboxylic acid functional groups, enabling peptide coupling and ring modification reactions. Also employed in the preparation of dyes and functionalized polymers where substituted anilines are required. Its methoxy groups enhance electron density, making it useful in reactions involving electrophilic substitution or metal-catalyzed cross-coupling.
