Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes where its nitro group facilitates coupling reactions. It also serves in the preparation of pharmaceuticals, acting as a building block for compounds with anti-inflammatory or analgesic properties, especially benzoic acid derivatives. Its carboxylic acid group and ester functionality allow for esterification, amidation, or further modifications, enabling incorporation into more complex molecules. Additionally, it finds use in agrochemical synthesis, contributing to the development of certain herbicides and plant growth regulators. It is also employed in organic chemistry research for creating new bioactive compounds, such as antimicrobials or antioxidants.
