Description

7WRW5VDZ79 3518-65-8 (Chloromethyl)sulfonyl chloride Chloromethanesulphonyl chloride Methanesulfonyl chloride, chloro- 4-01-00-03053 (Beilstein Handbook Reference) BRN 1811761 Chlorid kyseliny chlormethansulfonove [Czech] Chlormethansulfochlorid [Czech] Chlormethansulfonylchlorid [Czech] Chloromethanesulfonyl chloride EINECS 222-526-1 Chlorid kyseliny chlormethansulfonove Chlormethansulfochlorid Chlormethansulfonylchlorid UNII-7WRW5VDZ79 (CAS 3518-65-8), molecular formula CH2Cl2O2S and molecular weight 149.00 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7WRW5VDZ79 3518-65-8 (Chloromethyl)sulfonyl chloride Chloromethanesulphonyl chloride Methanesulfonyl chloride, chloro- 4-01-00-03053 (Beilstein Handbook Reference) BRN 1811761 Chlorid kyseliny chlormethansulfonove [Czech] Chlormethansulfochlorid [Czech] Chlormethansulfonylchlorid [Czech] Chloromethanesulfonyl chloride EINECS 222-526-1 Chlorid kyseliny chlormethansulfonove Chlormethansulfochlorid Chlormethansulfonylchlorid UNII-7WRW5VDZ79 (CH2Cl2O2S) 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 149.00 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
