Chemical Structure
Description
The occurrence of Chlorthiophos-sulfone is closely related to a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Chlorthiophos-sulfone (CAS 25900-20-3) is a high-purity analytical reference standard with the molecular formula C11H15Cl2O5PS2 and a molecular weight of 393.24 g/mol.
Based on its molecular formula C11H15Cl2O5PS2, Chlorthiophos-sulfone contains a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 393.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Chlorthiophos-sulfone 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.
