With few exceptions, by far most applications of tetrazolium salts (e. g., analytical, photographic, and biochemical) utilize their reducibility to the corresponding formazan dyes. Tetrazolium salts, due to their resistance to acid and oxidation and the presence of a positive charge, find use in other applications such as antistatic agents and phase transfer catalysts. Over the past two decades, there have been thousands of citations regarding the applications of tetrazolium salts. Most of these citations are patents with similar or overlapping and even identical claims. Any attempt at complete­ness would be futile. The applications are sorted where discernible, and the earliest or the broadest claims are cited.
