All three isomers have the chemical formula C sub 6 sub H sub 6 sub O sub 2 sub . Similar to other phenols, the hydroxyl groups on the aromatic ring of a benzenediol are weakly acidic . Each benzenediol can lose an H sup sup from one of the hydroxyls to form a type of phenolate ion. The Dakin oxidation is an organic redox reaction in which an ortho or para hydroxylated phenyl aldehyde or ketone reacts with hydrogen peroxide in base to form a benzenediol and a carboxylate. Overall, the carbonyl group is oxidized, and the hydrogen peroxide is reduced.

Merthiolate Iodine Formaldehyde MIF is a solution used in biomedical laboratories for concentration of stool sample s prior to microscopy microscopic investigation for parasite s. Concentration of stool is necessary in order to raise sensitivity of microscopy, as in non concentrated samples the likelihood of finding equivalents of actually present parasites is too low. MIF enables separation of different strata of stool matter, and sedimentation of stool particles that contain parasites usually parasite eggs . After application of MIF, usually centrifuge centrifugation is used for acceleration of sedimentation. The term Merthiolate indicates presence of thiomersal in the solution. Due to the hazardous qualities of thiomersal, it is no longer regularly added to MIF solutions any more, although the abbreviation MIF is still used for the solution. Thiomersal may nevertheless be added if its preservative qualities are particularly needed, for example if stool samples have to be preserved over longer time periods for example for teaching samples . ref name Dispensary Handbook Department of Infectious Diseases and Tropical Medicine.
