L-Aminobutyric acid (CAT: R007048) is a non-proteinogenic, four-carbon amino acid (C₄H₉NO₂) structurally related to alanine but with an extended carbon chain. It exists as the L-enantiomer, which can participate in biochemical pathways and serve as a chiral building block in organic synthesis. L-ABA is used in pharmaceutical research as an intermediate for synthesizing biologically active compounds, including neuroactive agents and metabolic modulators. It also finds applications in peptide synthesis, agrochemicals, and as a precursor in fine chemical production. Its simple structure, chirality, and functional versatility make it a valuable reagent in medicinal chemistry and stereoselective synthesis.
