List of iodophenols

There is a total of 19 iodophenols, corresponding to the different ways in which iodine atoms can be attached to the five carbon atoms in the benzene ring of the phenol molecule, excluding the carbon atom to which the hydroxy group is attached. Monoiodophenols have three isomers because there is only one iodine atom that can occupy one of three ring positions on the phenol molecule;

2-iodophenol 2-Iodophenol (''o''-iodophenol) is an aromatic organic compound with the formula IC6H4OH. It is a pale yellow solid that melts near room temperature. It undergoes a variety of coupling reactions in which the iodine substituent is replaced by a ne ...
