Chemical Structure

O,S-Diethyl Methylphosphonothioate CAS 2511-10-6 chemical structure

Description

As a certified reference material (CRM), O,S-Diethyl Methylphosphonothioate 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 O,S-Diethyl Methylphosphonothioate (CAS 2511-10-6), a certified reference material (molecular formula C5H13O2PS, MW 168.19 g/mol) for analytical method development and quality control.

Owing to a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, O,S-Diethyl Methylphosphonothioate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 168.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
