6-Amino-3-methyl-5-phenyl-1-(m-tolyl)pyridazin-4(1H)-one (CAS 89314-03-4) is a high-purity analytical reference standard with the molecular formula C18H17N3O and a molecular weight of 291.35 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 6-Amino-3-methyl-5-phenyl-1-(m-tolyl)pyridazin-4(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 6-Amino-3-methyl-5-phenyl-1-(m-tolyl)pyridazin-4(1H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
