Chemical Structure
Description
6-fluoro-5-methylpyrimidin-4-amine (C5H6FN3) contains a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
6-fluoro-5-methylpyrimidin-4-amine (CAS 18260-69-0) is a high-purity analytical reference standard with the molecular formula C5H6FN3 and a molecular weight of 127.12 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.
