Description
CATO supplies 1-(8-Chloro-1-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]quinoxalin-4-yl)piperidin-4-one O-(4-chlorobenzyl) oxime (CAS 400089-12-5), a certified reference material (molecular formula C22H17Cl2F3N6O, MW 509.31 g/mol) for analytical method development and quality control.
The molecular framework of 1-(8-Chloro-1-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]quinoxalin-4-yl)piperidin-4-one O-(4-chlorobenzyl) oxime (C22H17Cl2F3N6O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
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.
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.
