Applicazioni

2,6-Dichloro-1,4-benzoquinone is the suitable reagent used to in a study to evaluate the diffusion coefficients (D) for a family of quinones, nitroaromatics, ferrocenes and aromatic hydrocarbon compounds, in acetonitrile by single potential step chronoamperometry.1 It may be used in the preparation of 2,3,5-Trichloro-1,4-dihydroquinone, 2,3,5-trichloro-1,4-benzoquinone and 2,6-Dichloro-1,4-dihydroquinone.

Note

Store away from reducing agents and oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
