Description
CATO supplies 3,6-dichloropyrido[2,3-b]pyrazine (CAS 1350925-22-2), a certified reference material (molecular formula C7H13Cl2N3, MW 210.10 g/mol) for analytical method development and quality control.
Based on its molecular formula C7H13Cl2N3, 3,6-dichloropyrido[2,3-b]pyrazine contains a nitrile group, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 210.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
