CATO supplies 2-(Methylamino)-7-phenyl[1,3]thiazolo[4,5-d]pyridazin-4(5H)-one (CAS 1105192-28-6), a certified reference material (molecular formula C12H10N4OS, MW 258.30 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-(Methylamino)-7-phenyl[1,3]thiazolo[4,5-d]pyridazin-4(5H)-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 258.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
