Iodine monochloride is an interhalogen compound with the formula ICl. It is a red-brown chemical compound that melts near room temperature. Because of the difference in the electronegativity of iodine and chlorine, this molecule is highly polar and behaves as a source of I⁺. Discovered in 1814 by Gay-Lussac, iodine monochloride is the first interhalogen compound discovered.
