Benzeni

I benzene sono semplici idrocarburi aromatici costituiti da un anello di carbonio a sei membri con doppi legami alternati. Questa struttura fondamentale è un blocco costitutivo per numerosi composti chimici, inclusi prodotti farmaceutici, polimeri e coloranti. I benzene sono ampiamente utilizzati nella sintesi organica grazie alla loro stabilità e versatilità. Presso CymitQuimica, offriamo un'ampia gamma di benzene di alta qualità per supportare le vostre ricerche e applicazioni industriali.
