cyclobutanesulfonyl chloride CAS 338453-16-0 chemical structure

Description

CATO supplies cyclobutanesulfonyl chloride (CAS 338453-16-0), a certified reference material (molecular formula C4H7ClO2S, MW 154.62 g/mol) for analytical method development and quality control.

Structurally, cyclobutanesulfonyl chloride (C4H7ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 154.62 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), cyclobutanesulfonyl 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.
