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.
2-chloro-3-(chloromethyl)pyrazine (CAS 45660-95-5) is a high-purity analytical reference standard with the molecular formula C5H10Cl2N2 and a molecular weight of 169.05 g/mol.
Owing to chlorine substitution, 2-chloro-3-(chloromethyl)pyrazine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.05 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.
