Description

Potassiumd-Erythronate is a specialized potassium salt of erythronic acid, a four-carbon sugar acid derivative. This compound is valued for its role as a key chiral intermediate and building block in fine chemical synthesis, particularly within the pharmaceutical and nutraceutical sectors. It is essential for researchers and manufacturers developing active pharmaceutical ingredients (APIs), complex carbohydrates, and high-value biochemicals where stereochemical purity is critical.

Application

• Pharmaceutical Intermediate: Serves as a crucial chiral precursor in the synthesis of various therapeutic agents, including antiviral and antibiotic drugs.
• Biochemical Research: Used as a standard or reagent in enzymatic studies and metabolic pathway research involving sugar acids.
• Nutraceutical Synthesis: Employed in the production of advanced dietary supplements and conditionally essential nutrients.
• Cosmetic Ingredients: Acts as a starting material for synthesizing skin-conditioning agents and moisturizers with specific stereochemistry.
• Asymmetric Catalysis: Utilized as a ligand or auxiliary in catalytic processes requiring high enantioselectivity.
• Complex Carbohydrate Chemistry: A building block for the synthesis of oligosaccharides and glycoconjugates.

Quality Control

Our Potassiumd-Erythronate is produced 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 detailed results for key parameters such as assay, enantiomeric excess, and impurity profiles. Specifications can be aligned with cGMP and ICH guidelines for pharmaceutical applications upon request.

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 tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using a desiccant.
