Useful:

• General Description: 1,3,5,7-Tetramethyladamantane exhibits unusually low reactivity in chemical reactions, such as with nitric acid, due to the steric hindrance imposed by its four bridgehead methyl groups on the adamantane cage. This structural feature significantly retards its reaction kinetics, leading to selective oxidation and nitration products under aggressive conditions.
