Chemical Structure

(R)-O-(2,5-Dichlorophenyl) O-methyl phenylphosphonothioate CAS 73306-98-6 chemical structure

Description

As a certified reference material (CRM), (R)-O-(2,5-Dichlorophenyl) O-methyl phenylphosphonothioate 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.

CATO supplies (R)-O-(2,5-Dichlorophenyl) O-methyl phenylphosphonothioate (CAS 73306-98-6), a certified reference material (molecular formula C13H11Cl2O2PS, MW 333.17 g/mol) for analytical method development and quality control.

(R)-O-(2,5-Dichlorophenyl) O-methyl phenylphosphonothioate (C13H11Cl2O2PS) contains a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
