Chemical Structure
Description
(2Z)-N-(3-Fluorophenyl)-3-(pyrrolidin-1-yl)but-2-enamide (CAS 338792-87-3), molecular formula C14H17FN2O and molecular weight 248.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H17FN2O, (2Z)-N-(3-Fluorophenyl)-3-(pyrrolidin-1-yl)but-2-enamide 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 248.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
