Chemical Structure
Description
Structurally, 93-11-8 2-Naphthalenesulfonyl chloride Naphthalene-2-sulphonyl chloride EINECS 202-219-9 beta-Naphthalenesulfochloride Naphthalene-2-sulfonic acid chloride beta-Naphthalenesulfonyl chloride Naphthalene-2-sulfonyl chloride 2-Naphthylsulfonyl chloride NSC 133893 (C10H17ClO2S) 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 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 236.76 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.
