This compound is beta-homovaline hydrochloride, an analog of the essential amino acid valine. It is used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS) and other organic synthesis processes. The hydrochloride salt enhances its stability and solubility, making it a valuable building block for constructing peptides and proteins in pharmaceutical research, especially in the development of therapeutic peptides, hormones, and enzyme inhibitors. Its application is critical in producing peptides with high purity and specificity, which are essential for drug discovery and biochemical studies.
