Used primarily in organic synthesis, this compound serves as a key intermediate in the production of pharmaceuticals and advanced materials. Its structure, featuring both an ethynyl and a carboxylic acid group, makes it valuable for constructing complex molecules through reactions like Sonogashira coupling or esterification. It is particularly relevant in the development of active pharmaceutical ingredients (APIs) for therapeutic drugs, especially those targeting specific biological pathways. Additionally, its benzoic acid derivative properties allow it to be utilized in the creation of polymers and coatings with tailored functionalities.
