This compound, 2-(2-((tert-butyldimethylsilyl)oxy)phenyl)ethanol, is a specialty chemical intermediate in organic synthesis. It features a phenolic hydroxyl group protected as a tert-butyldimethylsilyl (TBDMS) ether, with a free primary alcohol functionality on the ethyl side chain. This protection strategy enables selective reactions at the alcohol or other sites during multi-step syntheses, particularly in the preparation of pharmaceuticals, fine chemicals, and bioactive compounds. The TBDMS group shields the phenol from unwanted side reactions, and it can be readily deprotected afterward to restore the active phenolic hydroxyl, preserving the integrity of sensitive functional groups throughout complex transformations.
