Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 6-Chloro-5-fluoropyridin-2-amine (CAS 1256808-75-9), a certified reference material (molecular formula C5H4ClFN2, MW 146.55 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/chlorine substitution, 6-Chloro-5-fluoropyridin-2-amine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.55 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.
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.
