| | p-Toluquinone Usage And Synthesis |
| Chemical Properties | yellow to brownish crystalline powder | | Uses | Methyl-p-benzoquinone imine is the products were the tetrahedral adducts. Synthesis of 2H-indazole-4,7-dione derivatives from3-phenylsydnone and p-toluquinone. A Michael addition of 2-methylcyclopentane-1,3-dione to various p-toluquinone imides exclusively afforded the sole products in a regiospecific manner. | | Uses | Methyl-p-benzoquinone (MBQ) can be used as a coating that forms an interface between the electrode and lithium (Li) electrolyte for the fabrication of redox flow batteries. It can be reduced during positive electrospray ionization mass spectroscopy (ESI MS) and can be potentially used during corona discharge. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 52, p. 5053, 1987 DOI: 10.1021/jo00231a048
