Chemical Structure

7-Fluoro-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione CAS 948015-78-9 chemical structure

Description

Structurally, 7-Fluoro-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione (C9H7FN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 194.16 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).

7-Fluoro-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione (CAS 948015-78-9), molecular formula C9H7FN2O2 and molecular weight 194.16 g/mol, is a CATO reference standard with documented purity and traceability.

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

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
