Used primarily as an intermediate in the synthesis of salicylic acid derivatives, including aspirin and other pharmaceuticals. It plays a key role in the production of dyes, UV absorbers, and optical brighteners due to its ability to form esters and amides with phenolic and amino groups. Commonly employed in the development of photoresists and specialty polymers where light sensitivity and thermal stability are required. Its reactivity makes it valuable in organic synthesis for introducing benzoyl functionalities in agrochemicals and pharmaceuticals.
