4-(Tert-butyl)-3-(2-ethoxyethyl)-3,4-dihydro-1H-benzo[e][1,2,4]triazepine-2,5-dione (CAS 866009-75-8), molecular formula C16H23N3O3 and molecular weight 305.37 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(Tert-butyl)-3-(2-ethoxyethyl)-3,4-dihydro-1H-benzo[e][1,2,4]triazepine-2,5-dione (C16H23N3O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 305.37 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
