Chemical Structure

3-Chlorothiete 1,1-dioxide CAS 15953-83-0 chemical structure

Description

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Chlorothiete 1,1-dioxide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.59 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.

3-Chlorothiete 1,1-dioxide (CAS 15953-83-0), molecular formula C3H5ClO2S and molecular weight 140.59 g/mol, is a CATO reference standard with documented purity and traceability.

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), 3-Chlorothiete 1,1-dioxide 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.
