Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-chloro-1-(2-ethylbutyl)-1H-pyrazolo[3,4-d]pyrimidine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 238.72 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).
