This compound, 3-((tert-Butyldimethylsilyl)oxy)-propanol, is a synthetically useful intermediate featuring a free hydroxyl group and a protected hydroxyl group via a tert-butyldimethylsilyl (TBDMS) moiety. It is employed in organic synthesis to enable selective reactions on the unprotected alcohol while safeguarding the other functional group during multi-step processes. This makes it particularly valuable in the preparation of pharmaceuticals, natural products, fine chemicals, and silicon-containing building blocks for advanced materials and coatings. The TBDMS protecting group offers excellent stability under a wide range of conditions and can be selectively removed under mild acidic or fluoride-mediated deprotection, streamlining synthetic workflows.
