Chemical Structure
Description
The occurrence of 3,6-Dichloropyridazin-4-ol hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,6-Dichloropyridazin-4-ol hydrochloride (CAS 1955519-50-2) is a high-purity analytical reference standard with the molecular formula C4H2Cl2N2OHCl and a molecular weight of 201.43 g/mol.
3,6-Dichloropyridazin-4-ol hydrochloride (C4H2Cl2N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
