In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Spontaneous formation and stabilization of radicals during the cocrystallization of alicyclic and peroxyalicyclic dicarboxylic acids, published in 2008-06-30, which mentions a compound: 610-09-3, Name is cis-Cyclohexane-1,2-dicarboxylic acid, Molecular C8H12O4, Quality Control of cis-Cyclohexane-1,2-dicarboxylic acid.
The cocrystn. of di(cis-2-carboxycyclohexylcarbonyl) peroxide and cyclohexane-1,2-dicarboxylic acid from aqueous solution affords stable 1-carboxycyclohexyl radicals, which were identified by EPR spectroscopy.
Here is just a brief introduction to this compound(610-09-3)Quality Control of cis-Cyclohexane-1,2-dicarboxylic acid, more information about the compound(cis-Cyclohexane-1,2-dicarboxylic acid) is in the article, you can click the link below.
