Description

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.

S-((6-Chloro-2-oxooxazolo[4,5-b]pyridin-3(2H)-yl)methyl) O,O-dimethyl phosphorodithioate (CAS 35570-72-0), molecular formula C9H10ClN2O4PS2 and molecular weight 340.74 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, S-((6-Chloro-2-oxooxazolo[4,5-b]pyridin-3(2H)-yl)methyl) O,O-dimethyl phosphorodithioate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures S-((6-Chloro-2-oxooxazolo[4,5-b]pyridin-3(2H)-yl)methyl) O,O-dimethyl phosphorodithioate 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.
