Chemical Structure
Description
6-Amino-2-ethyl-[3,4'-bipyridine]-5-carbonitrile (CAS 129090-38-6), molecular formula C13H12N4 and molecular weight 224.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Amino-2-ethyl-[3,4'-bipyridine]-5-carbonitrile (C13H12N4) 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 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 6-Amino-2-ethyl-[3,4'-bipyridine]-5-carbonitrile 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.
