Chemical Structure

Sodium-m-phosphate monohydrate CAS 10361-03-2 chemical structure

Description

Sodium-m-phosphate monohydrate (O3PNa) contains a phosphonate group. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

CATO supplies Sodium-m-phosphate monohydrate (CAS 10361-03-2), a certified reference material (molecular formula O3PNa, MW 101.96 g/mol) for analytical method development and quality control.

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-m-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.
