Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 291.34 g/mol gives 6-Ethyl-2-(p-tolyl)quinoline-4-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-Ethyl-2-(p-tolyl)quinoline-4-carboxylic acid (CAS 436091-46-2), a certified reference material (molecular formula C19H17NO2, MW 291.34 g/mol) for analytical method development and quality control.
The molecular framework of 6-Ethyl-2-(p-tolyl)quinoline-4-carboxylic acid (C19H17NO2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
