2-Cyclopentylcyclopentanone is a cyclic ketone bearing a cyclopentyl substituent alpha to the carbonyl group, giving a compact all-carbon bicyclic framework. It serves as a versatile non-heterocyclic building block for enolate alkylation, aldol condensation, and selective carbonyl reduction toward secondary alcohols. Branched cycloalkanone scaffolds of this type are also of interest in flavour and fragrance research and as reference materials in GC and GC-MS work. TCI supplies this liquid reagent in 25 mL and 500 mL packs; store tightly closed in a cool, dry, well-ventilated area and handle inside a fume hood.
