Chlorendic acid, or 1,4,5,6,7,7-hexachlorobicyclo()-hept-5-ene-2,3-dicarboxylic acid, is a chlorinated hydrocarbon used in the synthesis of some flame retardants and polymers. It is a common breakdown product of several organochlorine insecticides.
==Properties and identification==
Chlorendic acid is a white crystalline material with chemical formula 9464. It is also called HET acid, Hetron 92, Hetron 92C, hexachloro-''endo''-methylenetetrahydronaphthalic acid, 1,4,5,6,7,7-hexachloro-5-norbornene-2,3-dicarboxylic acid, and 1,4,5,6,7,7-hexachlorobicyclo()-5-heptene-2,3-dicarboxylic acid.
It is produced both as acid and as its anhydride. The anhydride has CAS number .
Chlorendic acid is slightly soluble in water and nonpolar organic solvents (e.g. benzene, hexane, carbon tetrachloride). It is easily soluble in slightly polar organic solvents (ethanol, methanol, acetone). When heated, it loses water at 200 °C, forming an anhydride with melting point of 230–235 °C. When subject to pyrolysis, it decomposes to hydrochloric acid and various chlorinated compounds. It is resistant to hydrolytic dechlorination. It readily forms salts with metals, and esters.
