It is an isomer of 3-chlorophthalic anhydride and a derivative of phthalic anhydride. PropertiesIt has a melting point of around 99 °C. Like most acid anhydrides, it can hydrolyze in the presence of water. ProductionIt can be produced by chlorination of phthalic anhydride. ApplicationsIt may be used to produce herbicides and pesticides, intermediates for active pharmaceutical ingredients and can be used as a monomer for the production of polyimides. References
