Diethyl [2,2'-biquinoline]-4,4'-dicarboxylate CAS 912-84-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Diethyl [2,2'-biquinoline]-4,4'-dicarboxylate.

CATO supplies Diethyl [2,2'-biquinoline]-4,4'-dicarboxylate (CAS 912-84-5), a certified reference material (molecular formula C24H20N2O4, MW 400.43 g/mol) for analytical method development and quality control.

The molecular framework of Diethyl [2,2'-biquinoline]-4,4'-dicarboxylate (C24H20N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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 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.

CATO manufactures Diethyl [2,2'-biquinoline]-4,4'-dicarboxylate 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.
