Description

Disodium Dihydrogen Phosphate [2R[2R*(4R*,8R*)]]-3,4-Dihydro-2,5,7,8-Tetramethyl-2-(4,8,12-Trimethyltridecyl)-2H-Benzopyran-6-Olate is a high-purity, organically derived phosphate ester of a tocopherol analog, offering a unique combination of antioxidant and emulsifying properties. This compound is critical for applications requiring a stable, water-soluble form of a potent antioxidant to protect sensitive ingredients from oxidative degradation. It is primarily needed by manufacturers in the pharmaceutical, advanced nutraceutical, and high-end cosmetic industries for formulating stable injectables, dietary supplements, and anti-aging skincare products.

Application

• Pharmaceutical Excipient: Used as a stabilizer and emulsifying agent in injectable formulations and lipid-based drug delivery systems.
• Nutraceutical Antioxidant: Serves as a key active or stabilizing ingredient in high-potency vitamin supplements and functional beverages.
• Cosmetic Stabilizer: Incorporated into serums, creams, and lotions to enhance the shelf-life and efficacy of oxidation-prone active ingredients like retinoids and vitamins.
• Biochemical Research: Utilized as a specialized reagent or standard in studies involving lipid peroxidation, antioxidant mechanisms, and membrane biology.
• Food Fortification (Specialized): Potential application in premium food-grade emulsions and fortified health foods where a soluble antioxidant is required.

Quality Control

Our Disodium Dihydrogen Phosphate Tocopherol Ester is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and isomer identification, residual solvent analysis, and heavy metal screening, to ensure it meets stringent specifications for pharmaceutical and nutraceutical use. Certificates of Analysis (COA) documenting compliance with relevant in-house or client-specific standards are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent decomposition. For long-term storage, consider desiccant or inert atmosphere conditions.
