Reagenzien

In der Analytik bezeichnet man als Reagens einen Stoff, der zur Identifikation eines anderen Stoffes gebraucht wird. Deswegen werden Reagenzien auch Nachweismittel genannt. Nach der Zugabe des Reagens tritt eine chemische Reaktion auf, die eine charakteristische Eigenschaftsänderung (z. B. Farbänderung oder Fällung) bewirkt. Dadurch können bestimmte Ionen oder funktionelle Gruppe nachgewiesen werden. In der Synthesechemie wird ein Reagens zur Modifikation eines Reaktanten benutzt und während der Reaktion verbraucht.
