3-((tert-Butyldimethylsilyl)oxy)-propanol
3-((tert-Butyldimethylsilyl)oxy)-propanol (CAS 73842-99-6) is a silyl-protected alcohol with the linear formula (CH3)3CSi(CH3)2OCH2CH2CH2OH and a molecular weight of 190.36 g/mol. This compound serves as a valuable building block in organic synthesis, particularly in multi-step chemical preparations. Its protected hydroxyl group allows for selective reactions elsewhere in a molecule, making it useful for constructing complex organic structures.

Organic Synthesis Intermediate
This compound is widely employed as an intermediate in the synthesis of more complex organic molecules. The tert-butyldimethylsilyl (TBS) ether protects the primary alcohol functionality, enabling selective reactions at other sites within a molecule.
Protecting Group Chemistry
The TBS group is a common protecting group for alcohols. 3-((tert-Butyldimethylsilyl)oxy)-propanol exemplifies its use, allowing chemists to manipulate other functional groups before deprotection to reveal the original alcohol.
Building Block for Specialty Chemicals
Its structure makes it a useful precursor for the synthesis of specialty chemicals, including potential pharmaceutical intermediates and materials science components.
