Chemical Structure
Description
The occurrence of 2-(4-(Tert-butyl)phenyl)-8-chloroquinoline-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(4-(Tert-butyl)phenyl)-8-chloroquinoline-4-carboxylic acid (CAS 862710-11-0) is a high-purity analytical reference standard with the molecular formula C20H18ClNO2 and a molecular weight of 339.82 g/mol.
2-(4-(Tert-butyl)phenyl)-8-chloroquinoline-4-carboxylic acid (C20H18ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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. 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.
