Cyclopentanone is a cyclic ketone.
Preparation and use
Upon treatment with barium hydroxide at elevated temperatures, adipic acid undergoes ketonization to give cyclopentanone.[2]
Cyclopentanone is commonly used as a fragrance. It is a versatile synthetic intermediate, being a precursor to cyclopentobarbital and jasmone.[3]
Cyclopentanone is also used to make cyclopentamine and also pentethylcyclanone.
