Chromic acid in glacial acetic acid solution oxidizes it to picene-quinone, picene-quinone carboxylic acid, and finally to phthalic acid.

This method is preferred over the " traditional " chromic acid bath for cleaning NMR tubes, because no traces of paramagnetic chromium can remain to spoil spectra.
