Methyl 8-fluoro-6-tosyl-5,6-dihydro-4H-benzo[b]thieno[2,3-d]azepine-2-carboxylate (CAS 2260804-47-3) is a high-purity analytical reference standard with the molecular formula C21H18FNO4S2 and a molecular weight of 431.50 g/mol.
Structurally, Methyl 8-fluoro-6-tosyl-5,6-dihydro-4H-benzo[b]thieno[2,3-d]azepine-2-carboxylate (C21H18FNO4S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 431.50 g/mol, it falls into the moderately-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).
As a certified reference material (CRM), Methyl 8-fluoro-6-tosyl-5,6-dihydro-4H-benzo[b]thieno[2,3-d]azepine-2-carboxylate 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.
