Chemical Structure

Diethylthiophosphoryl chloride CAS 3711-51-1 chemical structure

Description

CATO supplies Diethylthiophosphoryl chloride (CAS 3711-51-1), a certified reference material (molecular formula C4H10ClO2PS, MW 188.61 g/mol) for analytical method development and quality control.

Owing to a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Diethylthiophosphoryl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Diethylthiophosphoryl chloride 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.
