Used primarily as a protected intermediate in peptide synthesis and organic chemistry, this compound enables selective amine protection through its dual Boc (tert-butoxycarbonyl) groups. It is especially valuable in multi-step syntheses where controlled deprotection and coupling are required. The presence of the methylsulfanyl group allows for further functionalization or conversion, such as oxidation to sulfoxide or sulfone derivatives, expanding its utility in building complex molecules. Commonly employed in the preparation of heterocycles and modified amino acids, it supports the development of pharmaceuticals and bioactive compounds. Its stability under various reaction conditions makes it suitable for use in solid-phase and solution-phase synthesis strategies.
