AntiOxidant 24

CAS: 26741-53-7

AntiOxidant 24 is a chemical compound that inhibits the oxidation of organic compounds. It is an irreversible inhibitor of oxidation, which means it will not react with an oxidizing agent to form an intermediate or back-oxidized product. AntiOxidant 24 has been shown to be effective in analytical chemistry for the detection of cinnamic acid derivatives and inorganic acid. AntiOxidant 24 can also be used as a polymer film stabilizer, a fatty acid catalyst, and a sodium hydroxide solution.
