Chemical Structure
Description
CATO supplies 4-Chloro-N-(5-iodopyridin-2-yl)butanamide (CAS 338748-92-8), a certified reference material (molecular formula C9H10ClIN2O, MW 324.55 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H10ClIN2O, 4-Chloro-N-(5-iodopyridin-2-yl)butanamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 324.55 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.
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.
