(2E)-7-Chloro-2-{[(4-methylphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one CAS 338417-15-5

Description

(2E)-7-Chloro-2-{[(4-methylphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one (CAS 338417-15-5), molecular formula C16H13ClN2OS and molecular weight 316.81 g/mol, is a CATO reference standard with documented purity and traceability.

(2E)-7-Chloro-2-{[(4-methylphenyl)amino]methylidene}-3,4-dihydro-2H-1,4-benzothiazin-3-one (C16H13ClN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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