Used as a protected amine building block in organic synthesis, particularly in pharmaceutical and agrochemical industries. The tert-butyldimethylsilyl (TBS) group acts as a protecting group for the amine functionality, allowing selective reactions at other sites in the molecule. This compound is especially useful in multi-step syntheses where controlled deprotection is needed under mild conditions. Its stability under various reaction conditions makes it valuable in peptide synthesis and in the preparation of nitrogen-containing heterocycles. Commonly employed in research settings for the development of active pharmaceutical ingredients (APIs).
