Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for ester and carbonyl-containing compounds due to its stability and reactivity under controlled conditions. Commonly employed in the synthesis of fragrances and flavoring agents because of its ester functionality and mild odor profile. Also utilized in polymer chemistry as a monomer or modifier to influence polymer structure and degradation behavior. Its tert-butyl group allows for selective deprotection in multi-step synthesis, making it valuable in complex molecule assembly.
