Chemical Structure
Description
The occurrence of 5-((4-(Diethylamino)phenyl)imino)quinolin-8(5H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-((4-(Diethylamino)phenyl)imino)quinolin-8(5H)-one (CAS 101891-01-4) is a high-purity analytical reference standard with the molecular formula C19H19N3O and a molecular weight of 305.37 g/mol.
The molecular framework of 5-((4-(Diethylamino)phenyl)imino)quinolin-8(5H)-one (C19H19N3O) is characterized by a steroid core, 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. 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.
As a certified reference material (CRM), 5-((4-(Diethylamino)phenyl)imino)quinolin-8(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.
