Description

2-oxooxolane-3-sulfonyl chloride (CAS 40336-84-3), molecular formula C4H5ClO4S and molecular weight 184.60 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-oxooxolane-3-sulfonyl chloride (C4H5ClO4S) contains a carbohydrate-derived structure, a sulfone group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 184.60 g/mol, it falls into the medium-molecular-weight range. 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), 2-oxooxolane-3-sulfonyl 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.
