Chemical Structure

4-(5-Methyl-1H-pyrazol-3-yl)pyridine CAS 20007-63-0 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-(5-Methyl-1H-pyrazol-3-yl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 159.19 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).
