Disease relevance of mesitylene

• Novel efficient mesoporous solid acid catalyst UDCaT-4: dehydration of 2-propanol and alkylation of mesitylene [1].

High impact information on mesitylene

• The measured heat of formation indicates a third C-H bond dissociation energy (BDE) in 1,3,5-trimethylbenzene of 88.2 +/- 5.0 kcal/mol, indistinguishable from the C-H BDE in toluene or the first or second C-H BDEs in m-xylene [2].
• A subject exposed to controlled amounts of xylene and mesitylene was monitored by direct breath exhalation over a 4-hour period after exposure to the volatile organic compounds (VOCs) had stopped [3].
• Photolysis of 6-chloro-1,3-dimethyluracil and mesitylene in the presence of trifluoroacetic acid (TFA) at low temperature gave 1,3,5,7,9- and 1,3,6,8,10-pentamethylcyclooctapyrimidine-2,4-diones (1b, 1c) [4].
• Using 1,3,5-trimethylbenzene as reference compound, the rate constant of HO() reaction with trifluralin was obtained to be [Formula: see text] cm(3) molecule s(-1) at (300+/-5) K and atmospheric pressure [5].
• Concentrations of benzene, toluene, ethylbenzene, m/p-xylenes, o-xylene (BTEX) and 1,3,5-trimethylbenzene were determined in order to investigate their temporal and spatial distributions [6].

Biological context of mesitylene

• The biological indices of exposure for mesitylene have been proposed, taking the maximum allowable concentration (MAC) value in Poland (100 mg/m3) as the basis [7].
• The animals were exposed in the inhalation chambers to mesitylene vapors at the following concentrations: 0 ppm--group MES0; 25 ppm (125 mg/m3)--group MES25; 100 ppm (500 mg/m3)--group MES100 and 250 ppm (1,250 mg/m3)--group MES250 for 4 weeks (6 h/day, 5 days/week) [8].

Anatomical context of mesitylene

• These results indicate that inhalation exposure to mesitylene, like that to pseudocumene and hemimellitene, at concentrations close to the current hygiene standard value for trimethylbenzene, may produce long-term functional changes in the rat central nervous system [8].

Associations of mesitylene with other chemical compounds

• Citrate-capped gold nanoparticles (NPs) in aqueous solution were transferred directly into the organic solution mesitylene containing C-undecylcalix[4]-resorcinarene (C11-resorcinarene) [9].
• Rise of inhaled toluene, ethyl benzene, m-xylene, or mesitylene in rat blood after treatment with ethanol [10].
• Sensory respiratory irritation effects of trimethylbenzene isomers (TMBs) (hemimellitene, mesitylene and pseudocumene) in male Balb/C mice were investigated in conditions of acute exposure and in male Wistar rats in conditions of repeated 90-day inhalation exposure to pseudocumene [11].

Gene context of mesitylene

• After drying by evaporation, each sample residue was reconstituted in mesitylene and injected into a capillary GC-MS system via a splitless injection [12].
• The effects were most marked in the liver, where toluene caused increase in aniline hydroxylase and cytochrome P-450; o-xylene in aminopyrine N-demethylase and cytochrome b5; m-xylene and mesitylene in all the enzymes investigated [13].
• The absorption spectra of charge-transfer (CT) complexes of [60]fullerene with liquid methylbenzenes, viz. toluene, o-xylene, m-xylene, p-xylene and mesitylene have been investigated in CCl(4) medium [14].

Analytical, diagnostic and therapeutic context of mesitylene

• This paper presents data from both a human volunteer study looking at exposure to 1,3,5-trimethylbenzene (TMB) and an occupational hygiene study of a printing firm using screen wash containing technical grade TMB [15].
• Optical absorption spectra corresponding to surface plasmon resonance provided a broad band centered at 534 nm for C11-resorcinarene-capped gold NPs in mesitylene [9].
