Benzènes

Benzènes

Les benzènes sont des hydrocarbures aromatiques simples constitués d'un anneau de carbone à six membres avec des doubles liaisons alternées. Cette structure fondamentale est un bloc de construction pour de nombreux composés chimiques, y compris les produits pharmaceutiques, les polymères et les colorants. Les benzènes sont largement utilisés en synthèse organique en raison de leur stabilité et de leur polyvalence. Chez CymitQuimica, nous offrons une large gamme de benzènes de haute qualité pour soutenir vos recherches et applications industrielles.

  • 4,6-Dimethoxysalicylaldehyde

    CAS :
    4,6-Dimethoxysalicylaldehyde is a protonated molecule with a cyclohexane ring and 4 hydroxyl groups. Its chemical formula is C6H8O3. The compound has low bioavailability due to the presence of an intramolecular hydrogen bond that causes high redox potential. There are two amines on the aromatic ring which can coordinate with metal ions to form a complex. This compound's structural analysis has been conducted using X-ray crystallography, NMR spectroscopy, and IR spectroscopy. The structure of 4,6-dimethoxysalicylaldehyde is unsymmetrical due to the presence of two asymmetric carbon atoms in the molecule. It forms hydrogen bonds with other molecules due to its hydroxyl group and intramolecular hydrogen bond. Hydrogen bonding interactions occur between this compound and other molecules including water, alcohols, ammonia, amines, and carboxylic acids.

  • 2-Iodobenzoic acid

    CAS :

    2-Iodobenzoic acid is a synthetic compound that is used in the treatment of wastewater. It is produced by the reaction of benzoate and nitrite in the presence of sodium hydroxide. The intramolecular hydrogen atom transfer from the 2-iodobenzoic acid to benzoate is a reversible reaction. This process can be catalyzed by palladium, which has been shown to be effective in coupling 2-iodobenzoic acid with other compounds to produce cyclic peptides. The use of 2-iodobenzoic acid as a contraceptive has been investigated for its ability to inhibit acetylcholinesterase activity, which may lead to increased levels of acetylcholine and inhibition of muscle contractions.

  • 3,5-Dihydroxybenzaldehyde

    CAS :

    3,5-Dihydroxybenzaldehyde (DHBA) is a plant metabolite that is classified as a phenolic compound. It is found in many plants and has important biological functions such as the production of carotenoids or the cleavage of carotenoid to form other compounds. DHBA can be extracted from plant tissue with hydrochloric acid or carbon sources. It has been shown that DHBA inhibits the growth of soil bacteria by binding to amines and thus preventing them from reacting with substrates. This may be due to its ability to act as an electron donor, which could also explain its inhibitory activity on carotenoid cleavage.

  • 4-Formylbenzoic acid

    CAS :

    4-Formylbenzoic acid is an organic compound with the molecular formula CH2=C(O)CH=CHCO2H. It is a white solid that is soluble in water and has a strong, unpleasant odor. 4-Formylbenzoic acid has been shown to have affinity for binding to odorous molecules such as sulfur compounds, amines, and mercaptans. The binding of these molecules to the 4-formylbenzoic acid leads to a decrease in their odor concentration. This process can be done using electrochemical impedance spectroscopy or optical sensors. The oxidation of 4-formylbenzoic acid by trifluoroacetic acid produces 2-formylphenol and formaldehyde, which are themselves volatile compounds with an unpleasant odor. These reactions may be used as wastewater treatment methods. Langmuir adsorption isotherm may be used as an analytical method for measuring the concentration of 4-formylbenzoic acid
