Chemical Structure

O,O-Dimethylphosphorothioic acid sodium CAS 23754-87-2 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 O,O-Dimethylphosphorothioic acid sodium.

CATO supplies O,O-Dimethylphosphorothioic acid sodium (CAS 23754-87-2), a certified reference material (molecular formula C2H6O3PSNa, MW 164.09 g/mol) for analytical method development and quality control.

O,O-Dimethylphosphorothioic acid sodium (C2H6O3PSNa) contains a sulfone group, a phosphonate group, a carboxylic acid group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
