Description

S-B-Aminoisobutyric Acid CAS NO 4249-19-8 is a high-purity, non-proteinogenic amino acid derivative, specifically the S-enantiomer of 2-aminoisobutyric acid. This compound serves as a critical chiral building block and intermediate in the synthesis of complex pharmaceuticals and bioactive molecules. It is essential for research and production in the pharmaceutical, biotechnology, and fine chemical industries, where precise stereochemistry and high purity are paramount for efficacy and regulatory compliance.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the production of active pharmaceutical ingredients (APIs), including peptidomimetics and metabolic modulators.
• Biochemical Research: Used as a metabolic probe and in the study of amino acid transport and metabolism due to its non-metabolizable nature.
• Peptide Synthesis: Incorporated into synthetic peptides to alter conformation, stability, and biological activity.
• Agrochemical Development: Serves as a precursor in the synthesis of advanced herbicides and plant growth regulators.
• Cosmetic Actives: Potential ingredient in advanced skincare formulations targeting cellular repair and anti-aging.
• Diagnostic Reagents: Used in the manufacture of specialized reagents for clinical diagnostics and analytical standards.
