Compared with other compounds in its class, the molecular weight of 236.50 g/mol gives 5-Bromo-2-chloro-N-ethylpyrimidin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Bromo-2-chloro-N-ethylpyrimidin-4-amine (CAS 954221-06-8), molecular formula C6H7BrClN3 and molecular weight 236.50 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine/bromine substitution, an aromatic ring system, 5-Bromo-2-chloro-N-ethylpyrimidin-4-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
