Water-soluble tetrazolium salt

摘要

Thiazolyl tetrazolium salt solubility in the aqueous solution is increased to have on the phenyl ring which is bonded to the tetrazolium ring, the alkyl ammonium alkoxy substituents, the trimethyl ammonium propoxide group substituents, preferably. For example, thiazolyl tetrazolium salt solubility in the aqueous solution is increased, a compound of the general formula represented by the following formula (A-) _a, alkyl ammonium alkoxy substituents, the trimethyl ammonium propoxide group substituents, preferably and a phenyl ring which is bonded to a tetrazolium ring.
