N-Chlorosuccinimide ("NCS")is the organic compound with the formula C2H4(CO)2NCl. This white solid is used for chlorinations.[2] It is also used as a mild oxidant.[3] NCS is related to succinimide, but with N-Cl in place of N-H. The N–Cl bond is highly reactive, and NCS functions as a source of "Cl+".
