Description

D-Alanine, n-(Carboxymethyl)- (9Ci) is a specialized, non-proteinogenic amino acid derivative characterized by its D-configuration and a carboxymethyl substituent on the nitrogen. This unique structure makes it a valuable chiral building block and intermediate in advanced organic synthesis and pharmaceutical research. It is primarily utilized by research institutions and industrial R&D departments focused on developing novel peptides, enzyme inhibitors, and other bioactive compounds where stereochemistry is critical.

Application

• Pharmaceutical Intermediate: Key chiral synthon in the research and development of novel active pharmaceutical ingredients (APIs), particularly for peptide-based drugs and enzyme inhibitors.
• Biochemical Research: Used as a substrate or inhibitor in enzymatic studies to investigate enzyme specificity, mechanism, and for the development of diagnostic assays.
• Peptide Synthesis: Serves as a protected or modified amino acid building block in solid-phase and solution-phase peptide synthesis to introduce specific structural or functional properties.
• Chelating Agent Precursor: Acts as a starting material for the synthesis of specialized chelating ligands used in metal catalysis or medical imaging contrast agents.
• Asymmetric Synthesis: Employed as a chiral auxiliary or reagent in asymmetric catalytic reactions to induce stereoselectivity in the formation of new carbon-carbon or carbon-heteroatom bonds.

Quality Control

Our D-Alanine, n-(Carboxymethyl)- (9Ci) is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chiral purity verification by HPLC, to ensure it meets high-purity standards suitable for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept sealed to prevent moisture absorption, which can affect stability and handling properties.
