Chemical Structure
Description
The occurrence of Sodium L-ascorbyl-2-phosphate is closely related to a carbohydrate-derived structure, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Sodium L-ascorbyl-2-phosphate (CAS 66170-10-3), a certified reference material (molecular formula C6H6O9PNa, MW 276.07 g/mol) for analytical method development and quality control.
Structurally, Sodium L-ascorbyl-2-phosphate (C6H6O9PNa) contains a carbohydrate-derived structure, a phosphate ester group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 276.07 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Sodium L-ascorbyl-2-phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
