Chemical Structure
Description
Based on its molecular formula C7H10Cl2O3S, 4052-92-0 Benzoyl chloride, m-(chlorosulfonyl)- (7CI,8CI) Benzoyl chloride, 3-(chlorosulfonyl)- 3-(Chlorosulphonyl)benzoyl chloride m-(Chlorosulfonyl)benzoyl chloride 3-(Chlorosulfonyl)benzoyl chloride EINECS 223-759-1 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 245.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
