Beschreibung

Allgemeine Beschreibung

2-Naphthol (2OH) is a hydroxyarene molecule, which when electronically excited forms strong acid. Excited 2OH dissociates only in water. It has a slight phenolic odor. It is incompatible with strong oxidizing agents, strong bases, acid chlorides and acid anhydrides. It is one of the most commonly used fluorescence dye.

Anwendung

2OH has been used as a fluorescence indicator which changes fluorescence intensity at varied temperatures when embedded in aqueous Poly(vinly alcohol)/borax gel networks.
