Synthesis In the first step of the synthesis of heptylcyclopentanone, cyclopentanone and heptanal react by aldol condensation. The resulting reaction product is reduced by hydrogenation to heptylcyclopentanone.
Usage Heptylcyclopentanone is used as a fragrance in perfumes, deodorants, soaps, shampoos, skin creams, and cleaning products, among others. It gives them a jasmine, lavender, or honeysuckle-like scent. The compound is also used to make δ-dodecalactone.
