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.
CATO supplies Ethyl 4-(diethylamino)-6,8-difluoroquinoline-3-carboxylate (CAS 1216767-97-3), a certified reference material (molecular formula C16H18F2N2O2, MW 308.32 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 4-(diethylamino)-6,8-difluoroquinoline-3-carboxylate (C16H18F2N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures Ethyl 4-(diethylamino)-6,8-difluoroquinoline-3-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
