Cyclopropanecarbonyl chloride (also known as Cyclopropanecarboxylic acid chloride) is primarily used an intermediate in the manufacture of pharmaceutical and agrochemical products. e.g. Olaparib (AZD-2281, KU-59436), a small molecule inhibitor of the nuclear enzyme poly (ADP-ribose) polymerase (PARP) with potential chemosensitizing, radiosensitizing, and antineoplastic activities.
