10-(3,4-Dichlorobenzyl)-10H-benzo[b]pyrido[2,3-e][1,4]thiazine (CAS 400077-95-4) is a high-purity analytical reference standard with the molecular formula C18H12Cl2N2S and a molecular weight of 359.27 g/mol.
10-(3,4-Dichlorobenzyl)-10H-benzo[b]pyrido[2,3-e][1,4]thiazine (C18H12Cl2N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 10-(3,4-Dichlorobenzyl)-10H-benzo[b]pyrido[2,3-e][1,4]thiazine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
