Description

CATO manufactures 4,3':6',2":5",4'"-Quaterpyridine 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.

4,3':6',2":5",4'"-Quaterpyridine (CAS 2043946-53-6) is a high-purity analytical reference standard with the molecular formula C20H14N4 and a molecular weight of 310.35 g/mol.

The molecular framework of 4,3':6',2":5",4'"-Quaterpyridine (C20H14N4) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
