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 Ethyl 3-(5-bromopyridin-3-yl)-1,2,4-oxadiazole-5-carboxylate.
Ethyl 3-(5-bromopyridin-3-yl)-1,2,4-oxadiazole-5-carboxylate (CAS 850375-34-7), molecular formula C10H8BrN3O3 and molecular weight 298.09 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H8BrN3O3, Ethyl 3-(5-bromopyridin-3-yl)-1,2,4-oxadiazole-5-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
