Abstract

Hydrotetrazine compounds having antioxidant properties and uses thereof are described herein. These compounds may be dihydrotetrazines, tetrahydrotetrazines, or hexahydrotetrazines that can be utilized as antioxidants for use in thermoplastics, thermosets and elastomers; free radical inhibitors to stabilize reactive chemicals, such as monomers against free radical polymerizations; and as anticorrosion agents in coatings to protect against metal oxidation. The hydrogenated tetrazines can donate hydrogen atom equivalents to terminate radical chain reactions. These compounds can change colors to signal when oxidation has occurred, and can be further recycled by reduction reactions.
