Chemical Structure

6-Bromo-3-methyl-3,4-dihydro-2H-benzo[e][1,3]oxazine CAS 7331-78-4 chemical structure

Description

As a certified reference material (CRM), 6-Bromo-3-methyl-3,4-dihydro-2H-benzo[e][1,3]oxazine 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.

6-Bromo-3-methyl-3,4-dihydro-2H-benzo[e][1,3]oxazine (CAS 7331-78-4), molecular formula C37H36N3O6S2Na and molecular weight 705.82 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-Bromo-3-methyl-3,4-dihydro-2H-benzo[e][1,3]oxazine (C37H36N3O6S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 21.5, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 705.82 g/mol, it falls into the high-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.
