Used as a protected hydrazine derivative in organic synthesis, particularly in the preparation of hydrazides and heterocyclic compounds. It serves as a key intermediate in pharmaceutical synthesis where selective protection of functional groups is required. The tert-butyl and benzyl protecting groups allow for orthogonal deprotection strategies, enabling stepwise construction of complex molecules. Commonly employed in the development of protease inhibitors and other bioactive compounds. Also utilized in peptide chemistry and the synthesis of nitrogen-containing scaffolds due to its stability and controlled reactivity under acidic or basic conditions.
