Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 773-64-8 Benzenesulfonyl chloride, 2,4,6-trimethyl- 2-Mesitylenesulfonyl chloride (8CI) Mesitylene-2-sulphonyl chloride 3-11-00-00346 (Beilstein Handbook Reference) BRN 1107601 EINECS 212-257-8 Mesitylenesulfonyl chloride 2-Mesitylenesulfonyl chloride Mesitylsulfonyl chloride NSC 403295 2,4,6-Trimethylbenzenesulfonyl chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.75 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.
