2-Phospho-L-Ascorbic Acid trisodium salt, Cas # 66170-10-3 — an enhanced description of the original reagent: a stable, water-soluble, phosphorylated vitamin C derivative used as an antioxidant and biochemical reagent in research applications.

• Key specifications: Molecular weight ≈ 322.05; empirical formula C6H6Na3O9P; typical purity ≥95% (HPLC); white to off-white powder; supplied as 5 g presentation. (b2b.sigmaaldrich.com)
• Primary features: chemically stabilized ascorbate (improved shelf life vs. L-ascorbic acid), water-soluble, compatible with aqueous formulations. (b2b.sigmaaldrich.com)

Applications / benefits: commonly used as a cell-culture compatible antioxidant and cofactor to support collagen synthesis and differentiation (notably in mesenchymal stem cell and myoblast studies), for oxidative-stress protection in vitro, and as a stable vitamin C source in topical/cosmetic formulations and formulation development. For analytical and QC uses it also serves as a characterized reference in synthesis and method development. Research-use-only; not for diagnostic or therapeutic use. (fishersci.at)

Handling & storage: store tightly sealed in a cool, dry place; where stock solutions are required, prepare fresh or aliquot and store frozen (e.g., -20°C) to minimize degradation; unopened material may be stable for extended periods when stored per vial instructions. Check lot-specific Certificate of Analysis for water content and assay. (dcchemicals.com)
