The occurrence of 1-[(3-Bromophenyl)methyl]-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-[(3-Bromophenyl)methyl]-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one (CAS 866010-23-3), molecular formula C22H17BrN2O and molecular weight 405.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-[(3-Bromophenyl)methyl]-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one (C22H17BrN2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), 1-[(3-Bromophenyl)methyl]-5-phenyl-2,3-dihydro-1H-1,4-benzodiazepin-2-one 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.
