Chemical Structure

Sodium phosphotungstate tribasic hydrate puriss. p.a. CAS 12026-98-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sodium phosphotungstate tribasic hydrate puriss. p.a..

CATO supplies Sodium phosphotungstate tribasic hydrate puriss. p.a. (CAS 12026-98-1), a certified reference material (molecular formula O3WO4PNaH2O, MW 367.81 g/mol) for analytical method development and quality control.

The molecular framework of Sodium phosphotungstate tribasic hydrate puriss. p.a. (O3WO4PNaH2O) 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.

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 phosphotungstate tribasic hydrate puriss. p.a. 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.
