7.4.1. Physical Properties

Depending on the substituent, and to a lesser extent on the counterion, tetrazolium salts are generally crystalline colorless, or yellowish to orange solids. Although their solubility depends on the substituent pattern and the counterion, they are generally slightly soluble in water. Thus, tetrazolium
salts containing trimethylammonium groups on the aromatic substituents are very water soluble.1 Sulfonates and phosphonates are highly water soluble.192 They are thermally stable up to 215 °C. Some toxic properties have been described.12,13,16,194-196
