Used as an intermediate in organic synthesis, particularly in the production of fragrances and flavorings due to its pleasant aromatic character. It serves as a protecting group reagent in pharmaceutical synthesis, where the tert-butyl moiety can shield carboxylic acid functionalities during multi-step reactions. Also employed as a solvent or additive in polymerization processes, helping to control reaction rates and improve product consistency. Its stability under various reaction conditions makes it valuable in agrochemical and dye manufacturing.
