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>
