Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. It serves as a building block for gamma-aminobutyric acid (GABA) analogs, which are important in the development of central nervous system agents. Its acetyl-protected amine group allows for selective reactivity, making it valuable in peptide-like chain elongation and heterocycle formation. Also employed in the synthesis of prodrugs due to its metabolic stability and favorable solubility properties.
