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.
