2-(2-Chlorophenyl)-6-ethylquinoline-4-carboxylic acid CAS 667435-73-6

Description

As a certified reference material (CRM), 2-(2-Chlorophenyl)-6-ethylquinoline-4-carboxylic acid 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-(2-Chlorophenyl)-6-ethylquinoline-4-carboxylic acid (CAS 667435-73-6) is a high-purity analytical reference standard with the molecular formula C18H14ClNO2 and a molecular weight of 311.76 g/mol.

The molecular framework of 2-(2-Chlorophenyl)-6-ethylquinoline-4-carboxylic acid (C18H14ClNO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
