CATO supplies 6-Methyl-[1,2,4]triazolo[4,3-b]pyridazin-8-ol (CAS 18591-70-3), a certified reference material (molecular formula C6H6N4O, MW 150.14 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H6N4O, 6-Methyl-[1,2,4]triazolo[4,3-b]pyridazin-8-ol contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 150.14 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
