Chemical Structure
Description
6-Methyl-3,4-dihydro-2H-benzo[b][1,4]thiazine (CAS 58959-99-2), molecular formula C9H11NS and molecular weight 165.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Methyl-3,4-dihydro-2H-benzo[b][1,4]thiazine (C9H11NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 165.26 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 6-Methyl-3,4-dihydro-2H-benzo[b][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.
