Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Prednisolone Sodium Phosphate (CAS 125-02-0), molecular formula C21H27O8PNa and molecular weight 461.40 g/mol, is a CATO reference standard with documented purity and traceability.
Prednisolone Sodium Phosphate (C21H27O8PNa) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Prednisolone Sodium 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.
