Chemical Structure

N-(p-Tolyl)-[2,2'-biquinolin]-4-amine CAS 57115-21-6 chemical structure

Description

As a certified reference material (CRM), N-(p-Tolyl)-[2,2'-biquinolin]-4-amine 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.

N-(p-Tolyl)-[2,2'-biquinolin]-4-amine (CAS 57115-21-6), molecular formula C25H19N3 and molecular weight 361.44 g/mol, is a CATO reference standard with documented purity and traceability.

N-(p-Tolyl)-[2,2'-biquinolin]-4-amine (C25H19N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
