2-Ethyl-5-(4-nitrophenyl)-1,3,4-oxadiazole CAS 46713-46-6

Description

The molecular framework of 2-Ethyl-5-(4-nitrophenyl)-1,3,4-oxadiazole (C10H9N3O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
