The compound was first described by H. S. Verter, H. Porter, and R. Dominic in 1968. It was obtained by reacting tetrahydroxy-1,4-benzoquinone with oxalyl chloride in tetrahydrofuran. It is a yellow solid that can be crystallized as a tetrahydrofuran solvate, but could not be prepared in pure form.[1]
