Structurally, 80-41-1 2-Chloroethyl toluene-4-sulphonate Ethanol, 2-chloro-, 4-methylbenzenesulfonate Ethanol, 2-chloro-, p-toluenesulfonate (8CI) p-Toluenesulfonic acid, beta-chloroethyl ester Ethanol, 2-chloro-, 1-(4-methylbenzenesulfonate) 4-11-00-00249 (Beilstein Handbook Reference) AI3-02279 BRN 1968816 2-Chlorethylester kyseliny p-toluensulfonove [Czech] 2-Chloroethanol 4-methylbenzenesulfonate 2-Chloroethanol p-toluenesulfonate beta-Chloroethyl p-toluenesulfonate 2-Chloroethyl p-toluenesulfonate 2-Chloroethyl tosylate 2-Chloroethyl p-tosylate beta-Chloroethylester kyseliny p-toluensulfonove [Czech] EINECS 201-277-2 NSC 6079 p-Toluenesulfonic acid, 2-chloroethyl ester p-Toluenesulfonic acid-2-chloroethyl ester 2-(p-Toluenesulfonyloxy)ethyl chloride 2-Tosyloxyethyl chloride 2-Chlorethylester kyseliny p-toluensulfonove beta-Chloroethylester kyseliny p-toluensulfonove (C9H17ClO3S) 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 240.75 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.
