Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of local anesthetics such as lidocaine and related derivatives. Its sterically hindered aromatic structure makes it valuable in creating compounds with enhanced metabolic stability and selectivity. Also employed in fragrance formulations for its mild, sweet aldehyde character, contributing to woody and herbal scent notes in perfumery. Additionally, it serves as a building block in organic synthesis for creating specialty chemicals requiring bulky substituents to direct reaction pathways or improve lipophilicity.
