3-Phenyl-1,2,4-thiadiazole-5-sulfonyl chloride CAS 143947-88-0

Description

The occurrence of 3-Phenyl-1,2,4-thiadiazole-5-sulfonyl chloride is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Phenyl-1,2,4-thiadiazole-5-sulfonyl chloride (CAS 143947-88-0), molecular formula C8H5ClN2O2S2 and molecular weight 260.72 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Phenyl-1,2,4-thiadiazole-5-sulfonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.72 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.
