Chemical Structure

O,O’-Diethyl methylphosphonothioate CAS 6996-81-2 chemical structure

Description

The occurrence of O,O’-Diethyl methylphosphonothioate is closely related to a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

O,O’-Diethyl methylphosphonothioate (CAS 6996-81-2) is a high-purity analytical reference standard with the molecular formula C5H13O2PS and a molecular weight of 168.19 g/mol.

The molecular framework of O,O’-Diethyl methylphosphonothioate (C5H13O2PS) is characterized by a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.

CATO manufactures O,O’-Diethyl methylphosphonothioate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
