Chemical Structure
Description
Based on its molecular formula C14H12F3N3O, 1-[(Pyridin-3-yl)methyl]-3-[4-(trifluoromethyl)phenyl]urea 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 295.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1-[(Pyridin-3-yl)methyl]-3-[4-(trifluoromethyl)phenyl]urea (CAS 54528-11-9) is a high-purity analytical reference standard with the molecular formula C14H12F3N3O and a molecular weight of 295.26 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.
