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-Formylbenzoic acid

    CAS :
    <p>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</p>

  • 4-Bromobenzaldehyde

    CAS :
    <p>4-Bromobenzaldehyde is a chemical compound that belongs to the group of aromatic compounds. It has been shown to have a potent stimulatory effect on locomotor activity in mice, which may be due to its ability to increase levels of epidermal growth factor and gamma-aminobutyric acid in the brain. 4-Bromobenzaldehyde can be synthesized from 2,4-dibromophenol and anhydrous copper chloride in the presence of sodium hydroxide. The reaction mechanism for this synthesis is believed to involve an intermediate enamine form of 4-bromobenzaldehyde, which can then undergo hydrolysis into 2,4-dibromophenol and benzaldehyde. This product is used as a reagent in organic synthesis because it can be used to form esters with trifluoroacetic acid or hydrochloric acid in high yield.</p>
