Chemical Structure

6-Methyl-2-phenylquinoxaline CAS 25187-18-2 chemical structure

Description

CATO manufactures 6-Methyl-2-phenylquinoxaline 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.

6-Methyl-2-phenylquinoxaline (CAS 25187-18-2), molecular formula C15H12N2 and molecular weight 220.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Methyl-2-phenylquinoxaline (C15H12N2) 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.
