This compound is a selectively protected derivative of 3,5-dihydroxybenzyl alcohol, featuring two tert-butyldiphenylsilyl (TBDPS) groups on the phenolic hydroxyls at the 3- and 5-positions. The free primary benzylic alcohol enables selective reactions at that site while the bulky TBDPS groups offer steric hindrance and stability, preventing unwanted reactivity of the protected phenols during multi-step organic syntheses. This makes it valuable as a building block in the preparation of natural products, pharmaceuticals, and other fine chemicals requiring precise regioselectivity. The TBDPS protections are compatible with acidic and basic conditions and can be deprotected under mild fluoride-mediated conditions to reveal the free phenols without affecting the rest of the molecule.
