Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 145.59 g/mol gives Pyrazin-2-ylmethanamine dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pyrazin-2-ylmethanamine dihydrochloride (CAS 122661-25-0), molecular formula C5H7N3HCl and molecular weight 145.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, Pyrazin-2-ylmethanamine dihydrochloride 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. 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.
