2-(Methylthio)benzo[d]oxazole-5-sulfonyl chloride CAS 1803795-45-0

Description

The occurrence of 2-(Methylthio)benzo[d]oxazole-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.

2-(Methylthio)benzo[d]oxazole-5-sulfonyl chloride (CAS 1803795-45-0), molecular formula C8H6ClNO3S2 and molecular weight 263.72 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Methylthio)benzo[d]oxazole-5-sulfonyl chloride (C8H6ClNO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
