Verwenden
3-Hydroxyflavone is a reactant involved in studies of photochemically-induced dioxygenase-type CO-release reactivity; phase-transfer protection and deprotection of hydroxychromones; and O-methylation with di-Me carbonate. As a reactant it is involved in the synthesis of biologically active molecules including 2-chloropyridine derivatives for studies of antitumor agents and telomerase inhibitors; dihydrochromenopyrazines and chromenoquinoxalines. It is also involved in studies of its electrochemical properties using voltammetric methodologies.

läuterung methode
Recrystallise it from MeOH (m 169.5-170o), EtOH, aqueous EtOH (m 167o) or hexane. It has also been purified by repeated sublimation under high vacuum, and dried at high vacuum pumping for at least one hour [Bruker & Kelly J Phys Chem 91 2856 1987].
