Chemical Structure
Description
1-Cyclopropyl-2,3-dihydro-1H-pyrido[3,4-b][1,4]diazepin-4(5H)-one (CAS 1437481-38-3) is a high-purity analytical reference standard with the molecular formula C11H13N3O and a molecular weight of 203.24 g/mol.
1-Cyclopropyl-2,3-dihydro-1H-pyrido[3,4-b][1,4]diazepin-4(5H)-one (C11H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Cyclopropyl-2,3-dihydro-1H-pyrido[3,4-b][1,4]diazepin-4(5H)-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.
