Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.68 g/mol gives 4-Chloro-6-ethyl-2-phenylpyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-6-ethyl-2-phenylpyrimidine (CAS 89967-21-5), a certified reference material (molecular formula C12H11ClN2, MW 218.68 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-Chloro-6-ethyl-2-phenylpyrimidine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 218.68 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.
