Application
1,2-二氟苯 (1,2-DFB) 被用于研究邻-、间-和对-二氟苯离子的离解机制。它和 x 射线光电子能谱和程序升温脱附一起用来研究 1,2-DFB、1,2-二氯苯和 1,2-二溴苯在 Si (100) 2 x 1 上的室温吸附。。它还被用作转换金属配合物电化学研究的溶剂 。
用于过渡金属络合物的电化学研究的溶剂。

Threshold photoelectron photoion coincidence (TPEPICO) experiments have shown that o-, m-, and p-difluorobenzene ions dissociate via a common, ring-opened intermediate and not via ionized p-difluorobenzene. Rice-Ramsperger-Kassel-Marcus (RRKM) modeling of the experimental breakdown curves yields activation energies for the initial isomerization

In the present study, a hypothesis is presented for the prediction of the regioselectivity of cytochrome P-450 catalyzed hydroxylation of fluorobenzenes. The regioselectivity of the in vivo hydroxylation of fluorobenzene, 1,2-difluorobenzene, 1,3-difluorobenzene, 1,2,3-triluorobenzene, and 1,2,4-triflurobenzene could be predicted within 6%
