Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-(4-Chlorophenyl)-5-ethyl-1,2,4-oxadiazole (CAS 196301-93-6), a certified reference material (molecular formula C10H9ClN2O, MW 208.64 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Chlorophenyl)-5-ethyl-1,2,4-oxadiazole (C10H9ClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 3-(4-Chlorophenyl)-5-ethyl-1,2,4-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.
