Used primarily as an intermediate in the synthesis of pharmaceuticals and fine chemicals, this compound plays a key role in the development of active ingredients in anti-inflammatory and antioxidant agents. Its structure supports further chemical modifications, making it valuable in research settings for designing novel organic molecules. It is also employed in the preparation of specialty polymers where controlled oxidation resistance is required. Due to the presence of both carboxylic acid and phenolic functionalities, it serves as a building block in multi-step syntheses, particularly in routes involving conjugation or esterification reactions.
