Chemical Structure
Description
As a certified reference material (CRM), 2-(p-Tolyl)quinoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-(p-Tolyl)quinoline (CAS 24667-94-5), molecular formula C16H13N and molecular weight 219.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(p-Tolyl)quinoline (C16H13N) 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.
