Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 164.98 g/mol gives O-Methyl Phosphorodichloridothioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies O-Methyl Phosphorodichloridothioate (CAS 2523-94-6), a certified reference material (molecular formula CH3Cl2OPS, MW 164.98 g/mol) for analytical method development and quality control.
O-Methyl Phosphorodichloridothioate (CH3Cl2OPS) contains sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), O-Methyl Phosphorodichloridothioate 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.
