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.

  • 2,3,4-Trimethoxybenzoic acid

    CAS :
    2,3,4-Trimethoxybenzoic acid is a molecule that has been shown to stimulate epidermal growth. It is a methylating agent that can be used to produce 2-hydroxybenzoic acid from protocatechuic acid. The hydroxy group on the 2,3,4-trimethoxybenzoic acid binds to the chloride ion in the protocatechuic acid and removes it from the molecule. This reaction mechanism is supported by x-ray crystal structures of protocatechuic acid and 2,3,4-trimethoxybenzoic acid.
