Chemical Structure
Description
CATO supplies 2-(2,5-Dimethoxyphenyl)quinoline-4-carboxylic acid (CAS 485335-52-2), a certified reference material (molecular formula C18H15NO4, MW 309.32 g/mol) for analytical method development and quality control.
Structurally, 2-(2,5-Dimethoxyphenyl)quinoline-4-carboxylic acid (C18H15NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 309.32 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
