Chemical Structure
Description
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.
4-chloro-5-(trifluoromethyl)pyrimidin-2-amine (CAS 1201657-24-0) is a high-purity analytical reference standard with the molecular formula C5H9ClF3N3 and a molecular weight of 203.59 g/mol.
4-chloro-5-(trifluoromethyl)pyrimidin-2-amine (C5H9ClF3N3) contains fluorine/chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
