This hydrochloride salt is a Boc-protected derivative of 2-aminoacetamidine, serving as a key intermediate in organic synthesis. It is particularly valuable in peptide chemistry and pharmaceutical development for constructing guanidine-containing molecules, such as those mimicking arginine side chains. The compound facilitates the synthesis of biologically active agents with applications in anti-cancer therapeutics, neurological disorders, immunomodulators, and anti-infective drugs. The Boc group's stability and mild deprotection conditions enable precise control in multi-step reactions, enhancing efficiency in medicinal chemistry and biochemical research.
