Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(4-Methylphenyl)-2-(piperidin-1-yl)quinoline (CAS 339102-68-0), molecular formula C21H22N2 and molecular weight 302.41 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Methylphenyl)-2-(piperidin-1-yl)quinoline (C21H22N2) 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.
As a certified reference material (CRM), 3-(4-Methylphenyl)-2-(piperidin-1-yl)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.
