Chemical Structure
Description
3-(4-Bromophenyl)-5-(thiophen-2-yl)-1,2,4-oxadiazole (CAS 330459-34-2), molecular formula C12H7BrN2OS and molecular weight 307.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Bromophenyl)-5-(thiophen-2-yl)-1,2,4-oxadiazole (C12H7BrN2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
