Chemical Structure
Description
The occurrence of 2-((3-(Quinolin-2-ylmethoxy)phenyl)amino)benzoic acid hydrochloride 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-((3-(Quinolin-2-ylmethoxy)phenyl)amino)benzoic acid hydrochloride (CAS 146662-42-2) is a high-purity analytical reference standard with the molecular formula C23H18N2O3HCl and a molecular weight of 406.87 g/mol.
2-((3-(Quinolin-2-ylmethoxy)phenyl)amino)benzoic acid hydrochloride (C23H18N2O3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-((3-(Quinolin-2-ylmethoxy)phenyl)amino)benzoic acid hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
