    Abstract: A corrosion inhibitor active and method for reducing corrosion of a metal surface in contact with a corrosive environment is disclosed. The corrosion inhibitor active is an organic sulfonated compound that is derived from the sulfonation of one or more carboxylic acids, internal olefins, or alpha-olefins having a carbon chain length of 15 to 26 carbon atoms. The method of reducing corrosion includes contacting the metal surface with an effective amount of the corrosion inhibitor active. The corrosion inhibitor active is useful in high temperature corrosive environments, such as those found in oil and gas operations.
