Chemical Structure

Sodium orthophosphate dodecahydrate CAS 10101-89-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 135.97 g/mol gives Sodium orthophosphate dodecahydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sodium orthophosphate dodecahydrate (CAS 10101-89-0), a certified reference material (molecular formula O4PNaH2O, MW 135.97 g/mol) for analytical method development and quality control.

Sodium orthophosphate dodecahydrate (O4PNaH2O) contains a phosphate ester group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

As a certified reference material (CRM), Sodium orthophosphate dodecahydrate 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.
