The occurrence of 2,5-Dimethylthiophene-3-sulfonyl Chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,5-Dimethylthiophene-3-sulfonyl Chloride (CAS 97272-04-3), a certified reference material (molecular formula C6H7ClO2S2, MW 210.70 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 2,5-Dimethylthiophene-3-sulfonyl Chloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.70 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.
