Description

Disodium [2R-[2R*(4R*,8R*)]]-3,4-Dihydro-2,5,8-Trimethyl-2-(4,8,12-Trimethyltridecyl)-2H-1-Benzopyran-6-Yl Phosphate is a high-purity, water-soluble phosphate ester derivative of a tocopherol analog, designed for advanced applications requiring precise molecular structure. This compound matters for its role as a key synthetic intermediate or active component in the development of specialized pharmaceuticals and high-value nutraceuticals. Industries that require this specific stereochemistry and purity include pharmaceutical R&D, advanced cosmetic formulation, and the synthesis of novel bioactive compounds.

Application

• Pharmaceutical Intermediate: Critical for the synthesis of novel vitamin E analogs and other chromanol-based active pharmaceutical ingredients (APIs).
• Nutraceutical Research: Used in the development of advanced, bioavailable forms of antioxidant supplements.
• Cosmetic Actives: Serves as a precursor for stabilized, potent antioxidant ingredients in high-end skincare and anti-aging formulations.
• Biochemical Research: Employed as a standard or reagent in studies of lipid peroxidation, membrane biology, and antioxidant mechanisms.
• Specialty Chemical Synthesis: Acts as a building block for creating surfactants or stabilizers with specific chiral and antioxidant properties.
