摘要

A 2-substituted benzothiazolyl-3-substituted phenyl-5-substituted sulfonated phenyl-2H-tetrazolium salt represented by the following Formula (1):wherein, R¹ can bea hydrogen atom, a hydroxyl group, a methoxy group, and an ethoxy group; R² can be a nitro group, -OR⁴, and a carboxyl group; R³ is a hydrogen atom, a methyl group, or an ethyl group, while at least one is a methyl group or an ethyl group; R⁴ is a methyl group or an ethyl group; m is 1 or 2; n is an integer from 0 to 2; p is 0 or 1; n + p is 1 or greater; q is 1 or 2; when q is 2, the OR³'s are disposed adjacently to each other andmayform a ring; and X is a hydrogen atom or an alkali metal atom.
