Chemical Structure
Description
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.
5,11-Dihydro-6H-pyrido[2,3-β][1,4]benzodiazepin-6-one (CAS 885-70-1) is a high-purity analytical reference standard with the molecular formula C12H9N3O and a molecular weight of 211.22 g/mol.
The molecular framework of 5,11-Dihydro-6H-pyrido[2,3-β][1,4]benzodiazepin-6-one (C12H9N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 5,11-Dihydro-6H-pyrido[2,3-β][1,4]benzodiazepin-6-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.
