1. A composition comprising a compound of the formula:
-
wherein R1-R10 are selected from the group consisting of hydrogen and a carbon chain, wherein the carbon chain is saturated, unsaturated, linear, branched, cyclic, or polycyclic and can have heteroatoms attached;
wherein R1 and R2 are hydrogen and R10 is a carbon chain of one to 30 carbons when R10 is not hydrogen.

Abstract
The present invention provides new compounds that can be used as antioxidants for either molecules that do not conation ester groups or esters of alcohols that contain two or more ester groups per molecule wherein at least two of the ester groups are on adjacent carbons in the alcohol moiety. Copper ions can enhance the antioxidization activity of the new compounds. Compositions containing one of the new compound and methods of using the new compounds are disclosed.
