Eterocicli con azoto (N)
In questa categoria troverete un'ampia varietà di eterocicli contenenti azoto. Gli eterocicli sono catene di carbonio che formano un ciclo in cui almeno una posizione è occupata da un eteroatomo, in questo caso l'azoto. Questi composti sono fondamentali nella sintesi di prodotti farmaceutici, agrochimici e coloranti, offrendo una reattività e una stabilità uniche. Presso CymitQuimica, offriamo un'ampia selezione di eterocicli contenenti azoto di alta qualità per supportare le vostre ricerche e applicazioni industriali.
