Description

D-Alanine, n-(Methoxycarbonyl)- (9Ci) is a protected derivative of the non-proteinogenic D-amino acid, alanine. This high-purity chiral building block is essential for the controlled synthesis of peptides and peptidomimetics, offering precise stereochemical control. It is primarily utilized by research institutions and pharmaceutical companies engaged in advanced drug discovery, proteomics research, and the development of novel bioactive compounds.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for peptide-based therapeutics.
• Peptide Synthesis: Used in solid-phase and solution-phase peptide synthesis (SPPS) to incorporate D-alanine residues with a protected amine group, enabling complex peptide chain assembly.
• Proteomics & Biochemical Research: Serves as a standard or reagent in metabolic pathway studies, enzyme substrate investigations, and the study of amino acid racemization.
• Agrochemical Development: Employed in the synthesis of chiral ligands and active compounds for crop protection products.
• Material Science: Potential monomer or building block for designing specialized polymers and biomaterials with specific chiral properties.

Quality Control

Our D-Alanine, n-(Methoxycarbonyl)- (9Ci) is manufactured under a strict quality management system. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and chiral integrity, to ensure it meets exacting research and development standards. A detailed Certificate of Analysis (COA) providing full specifications and test results is supplied with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment and allowed to reach room temperature before opening to prevent moisture adsorption.
