Description

Disodium D-Glutamate is the disodium salt form of the D-isomer of the amino acid glutamic acid. This compound serves as a valuable chiral intermediate and building block in advanced organic synthesis and pharmaceutical research. It is particularly relevant for industries requiring high-purity, stereochemically defined components. Key applications include its use in the development of active pharmaceutical ingredients (APIs), biochemical research, and as a precursor for specialty chemicals.

Application

• Pharmaceutical Intermediate: A key chiral building block in the synthesis of specific APIs, peptides, and complex organic molecules.
• Biochemical Research: Used in enzymatic studies, metabolic pathway analysis, and as a standard or reagent in analytical laboratories.
• Food Science Research: Employed in studies related to flavor chemistry, umami taste receptors, and as a reference compound for analytical method development.
• Cosmetic Ingredient Synthesis: Acts as a precursor for the production of certain moisturizing or skin-conditioning agents.
• Asymmetric Synthesis: Utilized as a starting material or resolving agent in stereoselective chemical reactions.

Quality Control

Our Disodium D-Glutamate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) with key parameters including assay, enantiomeric purity, and impurity profiles. Specifications can be aligned with research-grade or higher purity standards as required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
