4-Hydroxy-2-phenylquinoline-3-carboxylic acid CAS 13180-35-3

Description

Compared with other compounds in its class, the molecular weight of 265.26 g/mol gives 4-Hydroxy-2-phenylquinoline-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Hydroxy-2-phenylquinoline-3-carboxylic acid (CAS 13180-35-3), molecular formula C16H11NO3 and molecular weight 265.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-Hydroxy-2-phenylquinoline-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
