Chemical Structure
Description
The molecular framework of 7-(Methylthio)-5,6-dihydro-4H-imidazo[4,5-d]pyridazin-4-one (C6H6N4OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
7-(Methylthio)-5,6-dihydro-4H-imidazo[4,5-d]pyridazin-4-one (CAS 3438-77-5) is a high-purity analytical reference standard with the molecular formula C6H6N4OS and a molecular weight of 182.20 g/mol.
