2,5-Bis(4-diethylaminophenyl)-1,3,4-oxadiazole CAS 1679-98-7

Description

2,5-Bis(4-diethylaminophenyl)-1,3,4-oxadiazole (CAS 1679-98-7) is a high-purity analytical reference standard with the molecular formula C22H28N4O and a molecular weight of 364.48 g/mol.

The molecular framework of 2,5-Bis(4-diethylaminophenyl)-1,3,4-oxadiazole (C22H28N4O) is characterized by a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures 2,5-Bis(4-diethylaminophenyl)-1,3,4-oxadiazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
