Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 250.09 g/mol gives 5-(4-Bromophenyl)pyrimidin-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(4-Bromophenyl)pyrimidin-2-amine (CAS 31483-56-4), a certified reference material (molecular formula C10H8BrN3, MW 250.09 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 5-(4-Bromophenyl)pyrimidin-2-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.09 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.
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.
