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-Dihydroxybenzaldehyde

    CAS :
    <p>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.</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>
