Description

The substance 5-norbornene-2,3-dicarboxylic anhydride has a purity of approximately 99.5 % and consists of two isomers, cis-5-norbrene-endo-2,3-dicarboxylic anhydride (99.2 %) and cis-5-norbreneexo-2,3-dicarboxylic anhydride (0.3 %). It has an estimated log Po/w = 2.3. Due to its chemical nature as an anhydride it readily hydrolyses into the free diacid, norbornene-2,3-dicarboxylic acid. Therefore, migration into aqueous foodstuffs will also lead to the presence of the two isomeric diacids. Melting point of the substance is 163-165 °C.
