Chemical Structure
Description
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.
CATO supplies 8-Ethyl-2-(pyridin-3-yl)quinoline-4-carboxylic acid (CAS 774587-14-3), a certified reference material (molecular formula C17H14N2O2, MW 278.31 g/mol) for analytical method development and quality control.
The molecular framework of 8-Ethyl-2-(pyridin-3-yl)quinoline-4-carboxylic acid (C17H14N2O2) is characterized by a steroid core, 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
