Chemical Structure
Description
The occurrence of 2-(3,4-Dichlorophenyl)-1-(4-(pyrrolidin-1-ylmethyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridin-5(4H)-yl)ethanone is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(3,4-Dichlorophenyl)-1-(4-(pyrrolidin-1-ylmethyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridin-5(4H)-yl)ethanone (CAS 145544-79-2) is a high-purity analytical reference standard with the molecular formula C19H22Cl2N4O and a molecular weight of 393.31 g/mol.
The molecular framework of 2-(3,4-Dichlorophenyl)-1-(4-(pyrrolidin-1-ylmethyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridin-5(4H)-yl)ethanone (C19H22Cl2N4O) is characterized by a steroid core, 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 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.
As a certified reference material (CRM), 2-(3,4-Dichlorophenyl)-1-(4-(pyrrolidin-1-ylmethyl)-6,7-dihydro-3H-imidazo[4,5-c]pyridin-5(4H)-yl)ethanone 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.
