Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
L-Ascorbic Acid 2-Phosphate Sesquimagnesium Salt Hydrate (CAS 113170-55-1) is a high-purity analytical reference standard with the molecular formula C12H12Mg3O18P2·xH2O and a molecular weight of 579.07 g/mol.
The molecular framework of L-Ascorbic Acid 2-Phosphate Sesquimagnesium Salt Hydrate (C12H12Mg3O18P2·xH2O) is characterized by a carbohydrate-derived structure, a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures L-Ascorbic Acid 2-Phosphate Sesquimagnesium Salt Hydrate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
