2-(4-Ethyl-phenyl)-quinoline-4-carboxylic acid 2-(4-ethyl-phenyl)quinoline-4-carboxylic acid 2-(4-ethylphenyl)quinoline-4-carboxylic acid 301320-96-7 CAS 301320-96-7 chemical structure

Description

2-(4-Ethyl-phenyl)-quinoline-4-carboxylic acid 2-(4-ethyl-phenyl)quinoline-4-carboxylic acid 2-(4-ethylphenyl)quinoline-4-carboxylic acid 301320-96-7 (C18H15NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
