CATO supplies 2-(4-Chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)isoquinolin-1(2H)-one (CAS 113293-11-1), a certified reference material (molecular formula C17H11ClN4O, MW 322.75 g/mol) for analytical method development and quality control.

The molecular framework of 2-(4-Chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)isoquinolin-1(2H)-one (C17H11ClN4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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.

As a certified reference material (CRM), 2-(4-Chlorophenyl)-3-(1H-1,2,4-triazol-1-yl)isoquinolin-1(2H)-one 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.
