Used primarily as a building block in organic synthesis, particularly in the pharmaceutical and agrochemical industries. Its ester groups allow for selective hydrolysis and decarboxylation, making it valuable in the preparation of carboxylic acids and ketones. Commonly employed in the synthesis of active pharmaceutical ingredients (APIs) where it serves as a precursor for introducing branched alkyl chains. Also utilized in the production of specialty polymers and fragrances due to its stability and reactivity profile. Its tert-butyl group provides steric hindrance, which can help control reaction selectivity in complex multi-step syntheses.
