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-Hydroxy-2-methoxybenzoic acid

    CAS :
    3-Hydroxy-2-methoxybenzoic acid (3HMB) is a phenolic compound that is found in the heartwood of Eucalyptus trees, fruits such as apples and cherries, and some vegetables. 3HMB has been shown to inhibit tumor necrosis factor-α (TNF-α) production by proinflammatory cytokines such as IL-1β and IL-6, which are produced by cells in response to infection or tissue injury. 3HMB also inhibits the activity of tyrosol oxygenase, which converts tyrosol to vanillic acid. Vanillic acid can be converted into vanillin, an important precursor for the synthesis of pigments that give fruits their color. 3HMB has been shown to inhibit the growth of cancer cells in vitro.
