4-Chloro-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide CAS 866131-06-8

Description

The occurrence of 4-Chloro-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide (CAS 866131-06-8), molecular formula C7H7ClO2S2 and molecular weight 222.71 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-Chloro-5,6-dihydro-4H-thieno[2,3-b]thiopyran 7,7-dioxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.71 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.
