Chemical Structure

2-Phenylquinoline-8-carboxylic acid CAS 5093-81-2 chemical structure

Description

The occurrence of 2-Phenylquinoline-8-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Phenylquinoline-8-carboxylic acid (CAS 5093-81-2), molecular formula C16H11NO2 and molecular weight 249.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Phenylquinoline-8-carboxylic acid (C16H11NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), 2-Phenylquinoline-8-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.
