Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3-Chloro-1-methyl-6,7-dihydro-5H-cyclopenta[c]pyridine-4-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.64 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).
3-Chloro-1-methyl-6,7-dihydro-5H-cyclopenta[c]pyridine-4-carbonitrile (CAS 1122022-83-6), molecular formula C10H9ClN2 and molecular weight 192.64 g/mol, is a CATO reference standard with documented purity and traceability.
