Chemical Structure

O,O-Dimethyl phosphoramidothioate CAS 17321-47-0 chemical structure

Description

CATO manufactures O,O-Dimethyl phosphoramidothioate 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.

CATO supplies O,O-Dimethyl phosphoramidothioate (CAS 17321-47-0), a certified reference material (molecular formula C2H8NO2PS, MW 141.13 g/mol) for analytical method development and quality control.

O,O-Dimethyl phosphoramidothioate (C2H8NO2PS) contains an amide group, a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
