Chemical Structure
Description
As a certified reference material (CRM), Sodium phosphate monohydrate 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.
CATO supplies Sodium phosphate monohydrate (CAS 10049-21-5), a certified reference material (molecular formula H2O4PNaH2O, MW 137.99 g/mol) for analytical method development and quality control.
The molecular framework of Sodium phosphate monohydrate (H2O4PNaH2O) is characterized by 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
