CATO supplies 287397-89-1 Diethyl Chlorothiophosphate-d10 NSC 43776-d10 O,O-(Diethyl-d10) Thiophosphoryl Chloride Phosphorochloridothioic Acid O,O-(Diethyl-d10) Ester (CAS 287397-89-1), a certified reference material (molecular formula C4D10ClO2PS, MW 198.67 g/mol) for analytical method development and quality control.
287397-89-1 Diethyl Chlorothiophosphate-d10 NSC 43776-d10 O,O-(Diethyl-d10) Thiophosphoryl Chloride Phosphorochloridothioic Acid O,O-(Diethyl-d10) Ester (C4D10ClO2PS) contains deuterium isotope labeling, a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
