Chemical Structure

Chloromethanesulfonamide CAS 21335-43-3 chemical structure

Description

Structurally, Chloromethanesulfonamide (CH4ClNO2S) contains a sulfone group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 129.57 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Chloromethanesulfonamide (CAS 21335-43-3), molecular formula CH4ClNO2S and molecular weight 129.57 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.
