Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-bromophenyl)-5-(pyrrolidin-2-yl)-1,2,4-oxadiazole hydrochloride.
CATO supplies 3-(4-bromophenyl)-5-(pyrrolidin-2-yl)-1,2,4-oxadiazole hydrochloride (CAS 1803608-62-9), a certified reference material (molecular formula C12H12BrN3OHCl, MW 330.61 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-bromophenyl)-5-(pyrrolidin-2-yl)-1,2,4-oxadiazole hydrochloride (C12H12BrN3OHCl) 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 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.
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.
