7-Chloro-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione (CAS 5177-39-9), molecular formula C9H7ClN2O2 and molecular weight 210.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Chloro-3,4-dihydro-1H-benzo[e][1,4]diazepine-2,5-dione (C9H7ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
