Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 361.24 g/mol gives Chlorthiophos distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Chlorthiophos (CAS 60238-56-4), a certified reference material (molecular formula C11H15Cl2O3PS2, MW 361.24 g/mol) for analytical method development and quality control.
The molecular framework of Chlorthiophos (C11H15Cl2O3PS2) is characterized by a sulfone group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), Chlorthiophos 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.
