title: Secondary products of itanoxone.
abstract: Itanoxone synthesis by Friedel-Crafts reaction between itaconic anhydride and 2-chlorobiphenyl was studied. Five isomers corresponding to possible impurities were prepared and studied to perfect a reliable and practical method to detect these impurities in itanoxone.
