Description

(3S)-3-Methyl-D-Aspartic Acid is a non-proteinogenic amino acid derivative of D-aspartic acid, featuring a methyl group at the 3-position. This specific stereochemistry makes it a valuable chiral building block and intermediate in advanced organic synthesis and pharmaceutical research. It is particularly sought after by research institutions and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors for developing novel compounds, including potential drug candidates and bioactive molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of new active pharmaceutical ingredients (APIs), especially for neurological and metabolic targets.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies and as a probe to investigate the function of aspartate receptors and transporters.
• Peptide Synthesis: Incorporated into synthetic peptides to modify their structure, stability, and biological activity for research and therapeutic applications.
• Asymmetric Synthesis: Serves as a chiral pool starting material or auxiliary for the stereoselective construction of complex molecules in fine chemical production.
• Neuroscience Research: Potential tool compound for studying the N-methyl-D-aspartate (NMDA) receptor subclass due to its structural similarity to aspartate.
