Chemical Structure
Description
2-Ethynyl-5-phenylpyridine (CAS 1196156-08-7), molecular formula C13H9N and molecular weight 179.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Ethynyl-5-phenylpyridine (C13H9N) 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 2-Ethynyl-5-phenylpyridine 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.
