Cetonas
As cetonas são compostos orgânicos caracterizados pela presença de um grupo carbonilo (C=O) ligado a dois átomos de carbono. Esses compostos são altamente versáteis e desempenham um papel crucial em várias reações químicas, incluindo oxidação, redução e condensação. As cetonas são intermediários essenciais na síntese de produtos farmacêuticos, fragrâncias e polímeros. Na CymitQuimica, oferecemos uma ampla gama de cetonas de alta qualidade para apoiar suas aplicações de pesquisa e industriais.
