In general, the hydroxyl group makes alcohols polar. 533-73-3, formula is C6H6O3, Because of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. Category: alcohols-buliding-blocks
Zaouak, Amira;Chouchane, Habib;Jelassi, Haikel research published 《 Kinetic and mechanism investigation on the gamma irradiation induced degradation of quizalofop-p-ethyl》, the research content is summarized as follows. An efficient gamma radiolytic decomposition of one of the extensively used herbicides in the world quizalofo-p-Et (QPE) was explored under different exptl. conditions. Aqueous solutions of QPE were irradiated by gamma rays emitted by a Cobalt 60 source. QPE aqueous solutions were irradiated at doses of 0.5-3 kGy with 26.31 Gy min-1 dose rate. Obtained results indicated that removal efficiency of 98.5% and 73% of QPE were obtained, resp., in absence and in presence of dissolved oxygen. Change of absorption spectra, pH effect and Total Organic Carbon (TOC) were carried out and studied. It was found that all absorption bands decreased with increasing irradiation dose and disappear totally after 3 kGy applied dose. Three pH conditions (pH = 10, pH = 6.2 and pH = 3) were applied in radiolytic degradation of QPE showing that the best removal efficiency has been found for neutral pH. Interestingly, the % TOC removal reaches 98% at 3 kGy indicated practically total mineralization. Furthermore, spectrophotometric analyses argued in favor of a pseudo-first-order kinetic of QPE degradation The resulting apparent rate constant value is approx. kapp = (0.012 ± 0.001) min-1. Finally, several byproducts such as 6-chloroquinoxalin -2-ol, 2-(4-hydroxy-phenyoxy) propionate, 1,4-hydroquinone, quinone, 4-chlorobenzene-1,2diol and 1,2,4-benzenetriol were identified by gas chromatog.-mass spectrometry (GC/MS) evidencing that radiation process starting with the fragmentation of the mol. involving the hydroxyl radical, which is generated by the radiolysis of water. Based on the identification intermediates, a degradation mechanistic schema of QPE has been proposed.
Category: alcohols-buliding-blocks, Benzene-1, 2, 4-triol, also known as hydroxyhydroquinone or 1, 2, 4-benzenetriol, belongs to the class of organic compounds known as hydroxyquinols and derivatives. Hydroxyquinols and derivatives are compounds containing a 1, 2, 4-trihydroxybenzene moiety. Benzene-1, 2, 4-triol is soluble (in water) and a very weakly acidic compound (based on its pKa). Outside of the human body, benzene-1, 2, 4-triol can be found in tea. This makes benzene-1, 2, 4-triol a potential biomarker for the consumption of this food product.
Benzene-1,2,4-triol is a benzenetriol carrying hydroxy groups at positions 1, 2 and 4. It has a role as a mouse metabolite.
1,2,4-Benzenetriol is a metabolite of benzene.
1,2,4-Benzenetriol is an intermediary metabolite of benzene that is present in roasted coffee beans. It is mutagenic and it causes cleaving of DNA single strands by the generation of reactive oxygen species.
1,2,4-Benzenetriol is a reactive molecule that has been shown to have hydrogen bonding interactions with copper chloride. It has been proposed as an inhibitor of methyltransferase, which is involved in the synthesis of methionine. Studies have shown that 1,2,4-Benzenetriol can also inhibit iron homeostasis and transfer reactions. The x-ray diffraction data for this compound shows that it forms a complex with the hydroxyl group. This complex is stabilized by hydrogen bonding interactions with the hydroxylic proton of the 1,2,4-benzenetriol molecule. 1,2,4-Benzenetriol has been shown to be toxic to HL-60 cells and K562 cells at concentrations greater than 5 mM. It has also been found to be effective against chlorogenic acids and other compounds in energy metabolism studies at concentrations between 0.5 and 2 mM., 533-73-3.
