3-(4-Bromo-3-chlorophenyl)-5-methyl-1,2,4-oxadiazole CAS 1199589-75-7

Description

The occurrence of 3-(4-Bromo-3-chlorophenyl)-5-methyl-1,2,4-oxadiazole is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Bromo-3-chlorophenyl)-5-methyl-1,2,4-oxadiazole (CAS 1199589-75-7), molecular formula C9H6BrClN2O and molecular weight 273.51 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-(4-Bromo-3-chlorophenyl)-5-methyl-1,2,4-oxadiazole (C9H6BrClN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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. 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 3-(4-Bromo-3-chlorophenyl)-5-methyl-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.
