UV-Vis spectroscopy, hplc-mass spectrometry and deuterium-labeling studies demonstrate that 4-alkyl-ortho-quinones cleanly rearrange to the isomeric 2-hydroxy-para-quinomethanes over a period of 10-20 minutes in aqueous buffer. These ortho-quinones are much more stable in organic solvents (CD3OH, CDCl3). Studies of the rate of rearrangement and of the introduction of pre-formed para-quinomethane to enzyme solution demonstrate that the quinomethanes, formed as secondary products, do not contribute to the inactivation of tyrosinase.

Studies of para-quinomethane formation during the tyrosinase-catalyzed oxidation of 4-alkylcatechols
