Uses
Cyclopentanone is common precursor to fragrances, especially those related to jasmine and jasmone. Examples include 2-pentyl- and 2-heptylcyclopentanone. It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital.
Cyclopentobarbital is a drug made from cyclopentanone.
Cyclopentanone is also used to make cyclopentamine, the pesticide pencycuron, and pentethylcyclanone.
