Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3-Chloro-6-(m-tolyl)pyridazine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.66 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).
