Chemical Structure
Description
The occurrence of 4,4'-Dimethyl-2,2'-biquinoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,4'-Dimethyl-2,2'-biquinoline (CAS 7654-51-5), a certified reference material (molecular formula C20H16N2, MW 284.35 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-Dimethyl-2,2'-biquinoline (C20H16N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,4'-Dimethyl-2,2'-biquinoline 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.
