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.

  • Methyl 3,4-dimethoxybenzoate

    CAS :
    Methyl 3,4-dimethoxybenzoate is an acetate extract that has been shown to inhibit tyrosinase activity. This compound also has a potent inhibitory effect on the production of p-hydroxybenzoic acid. Methyl 3,4-dimethoxybenzoate can be synthesized from protocatechuic acid and methoxy groups. It is a chemical reaction involving three steps: condensation, dehydration, and reduction. Tyrosinase is an enzyme in the melanin biosynthetic pathway that catalyzes the conversion of tyrosine to dopaquinone. Tyrosinase activity can be inhibited by methyl 3,4-dimethoxybenzoate through competitive inhibition or by its ability to reduce the availability of substrate for this enzyme.
