3-(4-(tert-Butyl)phenyl)-5-(2-chloropyridin-4-yl)-1,2,4-oxadiazole (CAS 1119396-18-7), molecular formula C17H16ClN3O and molecular weight 313.78 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-(tert-Butyl)phenyl)-5-(2-chloropyridin-4-yl)-1,2,4-oxadiazole (C17H16ClN3O) 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 its high hydrophobicity (logP), 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.
