Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 143.57 g/mol gives 6-chloro-5-methylpyrimidin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 6-chloro-5-methylpyrimidin-4-amine (CAS 14394-56-0), a certified reference material (molecular formula C5H6ClN3, MW 143.57 g/mol) for analytical method development and quality control.
Structurally, 6-chloro-5-methylpyrimidin-4-amine (C5H6ClN3) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 143.57 g/mol, it falls into the low-molecular-weight range. 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.
