Chemical Structure
Description
Based on its molecular formula C16H20N4O2HCl, 3-{5-[(4-Ethylpiperazin-1-yl)methyl]-1,2,4-oxadiazol-3-yl}benzaldehyde hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 336.82 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-{5-[(4-Ethylpiperazin-1-yl)methyl]-1,2,4-oxadiazol-3-yl}benzaldehyde hydrochloride (CAS 1184983-03-6) is a high-purity analytical reference standard with the molecular formula C16H20N4O2HCl and a molecular weight of 336.82 g/mol.
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.
