Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-chloropyrimidine-2-carbonitrile.
CATO supplies 4-chloropyrimidine-2-carbonitrile (CAS 898044-48-9), a certified reference material (molecular formula C5H8ClN3, MW 145.59 g/mol) for analytical method development and quality control.
Owing to a nitrile group, chlorine substitution, 4-chloropyrimidine-2-carbonitrile is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
