Naphtalènes

Naphtalènes

Les naphtalènes sont des hydrocarbures aromatiques polycycliques constitués de deux anneaux benzéniques fusionnés. Ces composés sont utilisés dans la synthèse de colorants, de résines et de produits pharmaceutiques. Les naphtalènes sont appréciés pour leur stabilité chimique et leurs propriétés aromatiques. Chez CymitQuimica, nous offrons une large sélection de naphtalènes de haute qualité pour soutenir vos recherches et applications industrielles.
