Description

D-Glutamicacid CAS NO 138-16-9 is the D-enantiomer of the amino acid glutamic acid, a key chiral building block in organic synthesis and biochemical research. This specific stereoisomer is crucial for applications requiring precise molecular configuration, such as in the development of pharmaceuticals and bioactive peptides. It is primarily sought by research institutions, pharmaceutical developers, and fine chemical manufacturers for use in chiral synthesis, metabolic studies, and as a precursor for specialized compounds.

Application

• Pharmaceutical Intermediate: Used in the synthesis of chiral drugs, peptides, and active pharmaceutical ingredients (APIs) where the D-configuration is required for specific biological activity or metabolic stability.
• Biochemical Research: Serves as a standard and reagent in enzymatic studies, metabolic pathway analysis, and neuroscience research related to glutamate receptors.
• Food & Flavor Industry: Employed in research for developing novel flavor enhancers and umami taste compounds, though the L-form is more common commercially.
• Cosmetic & Personal Care: Investigated for use in hair and skin care formulations as a moisturizing agent and a component of peptide-based actives.
• Agrochemical Synthesis: Acts as a chiral precursor in the development of specialized herbicides, pesticides, and plant growth regulators.
• Diagnostic Reagents: Utilized in the formulation of calibration standards and reagents for clinical diagnostic kits and analytical assays.

Quality Control

Our D-Glutamicacid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets high-purity standards suitable for research and synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, confirming identity, purity, and enantiomeric excess.

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 (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect purity and stability.
