Chemical Structure
Description
Owing to a nitrile group, sulfur-containing functionality, Pyridazine-4-carbothioamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.18 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).
