2,4,6-Trimethylphenol is a probe compound shown to react mainly with organic matter (3DOM*). 2,4,6-Trimethylphenol is rapidly oxidized by singlet oxygen in aqueous solution[1][2].
Peroxidatic substrates, catechol (CAT) and 2,4,6-trimethylphenol (TMP) were used as probes of thechloride dependent reactions catalyzed by chloroperoxidase (CPO). TMP is consumed only in the presence of chloride. TMP is a competitive inhibitor versus CAT, but CAT is a noncompetitive inhibitor versus TMP in chloride-dependent CPO-catalyzed peroxidation reactions. The ratio of TMP versus CAT consumed by the chloride-dependent CPO reaction in direct competition studies increases as the chloride concentration is increased from 1.0 to 400 mM[3].

Inhibition of humic substances mediated photooxygenation of furfuryl alcohol by 2,4,6-Trimethylphenol. Evidence for reactivity of the phenol with humic triplet excited states
Environ Sci Technol 2007 Sep 1;41(17):6066-73.PMID:17937283DOI:10.1021/es070656t.
To probe the reactivity of 2,4,6-Trimethylphenol with humic triplet excited states, we investigated its influence on the humic substances-mediated photooxygenation offurfuryl alcohol. Elliott soil humic and fulvic acids were employed for these experiments. When added in the concentration range of 10(-4) - 10(-3) M, 2,4,6-Trimethylphenol inhibited furfuryl alcohol photooxygenation to an extent depending on its concentration. The inhibiting effect decreased as the oxygen concentration was increased. By postulating that 2,4,6-Trimethylphenol competes with oxygen for reaction with humic triplet excited states and with furfuryl alcohol for reaction with singlet oxygen, we obtained kinetic laws describing the consumption profiles of furfuryl alcohol and 2,4,6-Trimethylphenol. Experimental rates of 2,4,6-Trimethylphenol and furfuryl alcohol loss could be satisfactorily fitted with 1.09-1.16 for the ratio k2/k3, where k2 and k3 are the reaction rate constants of humic triplet excited states with oxygen and 2,4,6-Trimethylphenol, respectively. These types of experiments could be extended to a variety of substrates to measure their reaction rate constants with humic triplet excited states.
Gas-phase acidities and O-H bond dissociation enthalpies of phenol, 3-methylphenol, 2,4,6-Trimethylphenol, and ethanoic acid
J Phys Chem A 2006 Sep 7;110(35):10392-403.PMID:16942044DOI:10.1021/jp0627426.
Energy-resolved, competitive threshold collision-induced dissociation (TCID) methods are used to measure the gas-phase acidities of phenol, 3-methylphenol, 2,4,6-Trimethylphenol, and ethanoic acid relative to hydrogen cyanide, hydrogen sulfide, and the hydroperoxyl radical using guided ion beam tandem mass spectrometry. The gas-phase acidities of Delta(acid)H298(C6H5OH) = 1456 +/- 4 kJ/mol, Delta(acid)H298(3-CH3C6H4OH) = 1457 +/- 5 kJ/mol, Delta(acid)H298(2,4,6-(CH3)3C6H2OH) = 1456 +/- 4 kJ/mol, and Delta(acid)H298(CH3COOH) = 1457 +/- 6 kJ/mol are determined. The O-H bond dissociation enthalpy of D298(C6H5O-H) = 361 +/- 4 kJ/mol is derived using the previously published experimental electron affinity for C6H5O, and thermochemical values for the other species are reported. A comparison of the new TCID values with both experimental and theoretical values from the literature is presented.
Humic substances mediated phototransformation of 2,4,6-Trimethylphenol: a catalytic reaction
Photochem Photobiol Sci 2005 Jun;4(6):451-3.PMID:15920627DOI:10.1039/b416925e.
Humic substances at a concentration of 0.42 mmol l(-1) of carbon are able to phototransform up to 0.68 mmol l(-1) of 2,4,6-Trimethylphenol upon irradiation at 365 nm, which shows that a catalytic reaction is operating.
Bacterial metabolism of 2,6-xylenol
Appl Environ Microbiol 1989 Nov;55(11):2904-8.PMID:16348052DOI:10.1128/aem.55.11.2904-2908.1989.
Strain DM1, a Mycobacterium sp. that utilizes 2,6-xylenol, 2,3,6-trimethylphenol, and o-cresol as sources of carbon and energy, was isolated. Intact cells of Mycobacterium strain DM1 grown with 2,6-xylenol cooxidized 2,4,6-Trimethylphenol to 2,4,6-trimethylresorcinol. 4-Chloro-3,5-dimethylphenol prevents 2,6-xylenol from being totally degraded; it was quantitatively converted to 2,6-dimethylhydroquinone by resting cells. 2,6-Dimethylhydroquinone, citraconate, and an unidentified metabolite were detected as products of 2,6-xylenol oxidation in cells that were partially inactivated by EDTA. Under oxygen limitation, 2,6-dimethylhy-droquinone, citraconate, and an unidentified metabolite were released during 2,6-xylenol turnover by resting cells. Cell extracts of 2,6-xylenol-grown cells contained a 2,6-dimethylhydroquinone-converting enzyme. When supplemented with NADH, cell extracts catalyzed the reduction of 2,6-dimethyl-3-hydroxyquinone to 2,6-dimethyl-3-hydroxyhydroquinone. Since a citraconase was also demonstrated in cell extracts, a new metabolic pathway with 2,6-dimethyl-3-hydroxyhydroquinone as the ring fission substrate is proposed.
Transformation of 2,4,6-Trimethylphenol and furfuryl alcohol, photosensitised by Aldrich humic acids subject to different filtration procedures
Chemosphere 2013 Jan;90(2):306-11.PMID:22921648DOI:10.1016/j.chemosphere.2012.07.013.
Suspended particles in a system made up of Aldrich humic acids (HAs) in water account for about 13% of the total HA mass, 10-11% of the organic carbon and 9-11% of radiation extinction in the UVA region. Extinction would be made up of radiation scattering (less than one third) and absorption (over two thirds). The contribution of particles to the degradation rates of trimethylphenol and furfuryl alcohol (FFA) (probes of triplet states and (1)O(2), respectively) was lower than 10% and possibly negligible. The results indicate that triplet states and (1)O(2) occurring in the solution bulk are mostly produced by the dissolved HA fraction. Experimental data would not exclude production of (1)O(2) in particle hydrophobic cores, unavailable for reaction with FFA. However, the limited to negligible particle fluorescence places an upper limit to particle core photoactivity.
