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.

  • 3,5-Dimethylbenzaldehyde

    CAS :
    <p>3,5-Dimethylbenzaldehyde is an organic compound that is a colorless liquid. It has a chemical formula of C9H12O2 and is classified as an aldehyde. 3,5-Dimethylbenzaldehyde can be synthesized by the reaction of isopropyl palmitate with xylene in the presence of carbon as a source. The reaction time required for this synthesis is approximately one day. The major products of this reaction are 3,5-dimethylbenzaldehyde and 2-methylbutanal. This reaction mechanism can also be used to determine the concentration of urinary metabolites in human urine samples. Analysis of these samples requires an organic solvent such as hexane or dichloromethane. Kinetic data was collected from the rate at which zinc powder reacts with 3,5-dimethylbenzaldehyde over time at different concentrations. A kinetic experiment was conducted using c–h bond activation to produce 3,5-dimethoxy</p>

  • 2-Iodobenzoic acid

    CAS :
    <p>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.</p>
