Chemical Structure
Description
(E)-4-(Furan-2-yl)-2-((4-(trifluoromethyl)phenyl)amino)but-3-enenitrile (CAS 834883-57-7), molecular formula C15H11F3N2O and molecular weight 292.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (E)-4-(Furan-2-yl)-2-((4-(trifluoromethyl)phenyl)amino)but-3-enenitrile (C15H11F3N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 292.26 g/mol, it falls into the medium-molecular-weight range. 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.
