Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 3-Amino-1-methyl-5-(trifluoromethyl)pyridin-2(1H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
3-Amino-1-methyl-5-(trifluoromethyl)pyridin-2(1H)-one (CAS 1553950-73-4), molecular formula C7H7F3N2O and molecular weight 192.14 g/mol, is a CATO reference standard with documented purity and traceability.
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.
