2-((4-Chlorophenyl)sulfonyl)-4,5-dimethyl-3,6-dihydro-2H-1,2-thiazine 1-oxide CAS 91494-76-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4-Chlorophenyl)sulfonyl)-4,5-dimethyl-3,6-dihydro-2H-1,2-thiazine 1-oxide.

2-((4-Chlorophenyl)sulfonyl)-4,5-dimethyl-3,6-dihydro-2H-1,2-thiazine 1-oxide (CAS 91494-76-7), molecular formula C12H14ClNO3S2 and molecular weight 319.83 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, 2-((4-Chlorophenyl)sulfonyl)-4,5-dimethyl-3,6-dihydro-2H-1,2-thiazine 1-oxide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.83 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
