CATO supplies 3406-84-6 4,4'-Biphenyldisulfonyl chloride (8CI) (1,1'-Biphenyl)-4,4'-disulfonyl dichloride 4,4'-Bis(phenylsulphonyl) dichloride 4,4'-Biphenylylenedisulfonyl chloride p,p'-Diphenyldisulfonyl chloride EINECS 222-293-6 NSC 2062 (CAS 3406-84-6), a certified reference material (molecular formula C12H20Cl2O4S2, MW 363.32 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H20Cl2O4S2, 3406-84-6 4,4'-Biphenyldisulfonyl chloride (8CI) (1,1'-Biphenyl)-4,4'-disulfonyl dichloride 4,4'-Bis(phenylsulphonyl) dichloride 4,4'-Biphenylylenedisulfonyl chloride p,p'-Diphenyldisulfonyl chloride EINECS 222-293-6 NSC 2062 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 363.32 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
