Description

(S)-Isopropyl 2-Aminopropanoate Methanesulfonic Acid Salt is a high-purity chiral building block and intermediate of significant importance in advanced organic synthesis. Its value lies in providing a protected, enantiomerically pure form of alanine, facilitating the controlled introduction of the (S)-2-aminopropanoate moiety into complex target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and fine chemical industries, particularly for the development of active pharmaceutical ingredients (APIs), peptides, and other biologically active compounds where stereochemical integrity is paramount.

Application

• Pharmaceutical Intermediate: Key chiral building block for the synthesis of enantiomerically pure Active Pharmaceutical Ingredients (APIs).
• Peptide Synthesis: Used as a protected amino acid derivative in solid-phase and solution-phase peptide chemistry.
• Asymmetric Synthesis: Serves as a precursor for chiral catalysts, ligands, and auxiliaries in stereoselective transformations.
• Agrochemical Research: Intermediate in the development of chiral pesticides and herbicides with enhanced efficacy and selectivity.
• Fine Chemical Production: Valuable synthon for creating complex, high-value specialty chemicals and flavors/fragrances.
• Academic & R&D: Critical reagent for methodological development in organic chemistry and medicinal chemistry research programs.
