Compared with other compounds in its class, the molecular weight of 146.58 g/mol gives Pyrimidine-4,6-diamine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pyrimidine-4,6-diamine hydrochloride (CAS 5468-67-7) is a high-purity analytical reference standard with the molecular formula C4H6N4HCl and a molecular weight of 146.58 g/mol.
Owing to a nitrile group, chlorine substitution, Pyrimidine-4,6-diamine hydrochloride is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.58 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.
