Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 297.65 g/mol gives Chlorthion distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chlorthion (CAS 500-28-7), a certified reference material (molecular formula C8H9ClNO5PS, MW 297.65 g/mol) for analytical method development and quality control.
Structurally, Chlorthion (C8H9ClNO5PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 297.65 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), Chlorthion 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.
