Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-(2-Chlorophenoxy)-2-(4-chlorophenyl)quinoline-4-carboxylic acid (CAS 477886-56-9), a certified reference material (molecular formula C22H13Cl2NO3, MW 410.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H13Cl2NO3, 3-(2-Chlorophenoxy)-2-(4-chlorophenyl)quinoline-4-carboxylic acid contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 410.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
