Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl Dichlorothiophosphate.
Ethyl Dichlorothiophosphate (CAS 1498-64-2) is a high-purity analytical reference standard with the molecular formula C2H5Cl2OPS and a molecular weight of 179.01 g/mol.
Ethyl Dichlorothiophosphate (C2H5Cl2OPS) contains sulfur-containing functionality, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Ethyl Dichlorothiophosphate 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.
