The photolysis of o-tolualdehyde by natural sunlight has been investigated at the large outdoor European Photoreactor (EUPHORE) in Valencia, Spain. The photolysis rate coefficient was measured directly under different solar flux levels, with values in the range j(o-tolualdehyde) = (1.62-2.15)

The inhibition kinetics on the diphenolase activity of mushroom tyrosinase by some alkylbenzaldehydes has been investigated. The results show that the alkylbenzaldehydes assayed can lead to reversible inhibition to the enzyme; o-tolualdehyde and m-tolualdehyde are mixed-type inhibitors and p-alkylbenzaldehydes are

Mouse hepatic microsomal enzymes catalyzed the oxidation of o-, m-, and p-tolualdehydes, intermediate metabolites of xylene, to the corresponding toluic acids. Cofactor requirement for the catalytic activity indicates that the microsomes contain NAD- and NADPH-dependent enzymes for this reaction. GC/MS
