Anwendungen

1,2-Difluorobenzene(1,2-DFB) has been used to study the mechanism of dissociation of o-, m- and p-difluorobenzene ions by threshold photoelectron photoion coincidence spectroscopy. It has been used to study the room temperature adsorption of 1,2-DFB, 1,2-dichlorobenzene and 1,2-dibromobenzene on Si(100)2x1 by X-ray photoelectron spectroscopy and temperature programmed desorption. It is used as solvent in electrochemical studies on transition metal complexes. It is also applied as a solvent useful for electrochemical studies on transition metal complexes.

Bemerkungen

Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Keep away from ignition sources. Protect against electrostatic charges.
