Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of herbicides and fungicides. It serves as a building block in organic reactions due to the reactivity of both the nitrile and carboxylic acid functional groups. Commonly employed in the preparation of heterocyclic compounds, including benzoxazoles and quinazolines, which are found in bioactive molecules. Also utilized in research for developing new cyanide-based coupling agents and in the modification of dyes and pigments for improved stability and solubility.
