Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N-(2-Fluorophenyl)-2-(4-hydroxyphenoxy)-N-methylpropanamide (CAS 256412-88-1), a certified reference material (molecular formula C16H16FNO3, MW 289.30 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H16FNO3, N-(2-Fluorophenyl)-2-(4-hydroxyphenoxy)-N-methylpropanamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.30 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.
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.
