(But-3-yn-1-yloxy)(tert-butyl)dimethylsilane（Cat No.:L011086）is a silyl-protected alkyne featuring a terminal but-3-yn-1-yloxy group bonded to a tert-butyl-dimethylsilyl (TBS) protecting group. This compound is widely used in organic synthesis to temporarily protect hydroxyl groups during multistep reactions, especially in complex molecule and natural product synthesis. The TBS group provides excellent stability under basic and mildly acidic conditions, allowing selective deprotection when needed. The alkyne functionality enables further transformations such as cycloadditions or metal-catalyzed couplings, making this molecule a valuable intermediate in constructing diverse chemical architectures in research and development.
