Abstract:
A class of compounds of monosulfonic phenyltetrazole, with the structure of 2-(R1 phenyl)-5 (2-sulfonic phenyl)-2H-tetrazole. The 2-sulfonic phenyl tetrazolium salt of this invention has advantages of low toxicity, short synthetic route, easy control of purity and quality. As the 2-sulfonic phenyl tetrazolium salts has almost no absorption at 450 nm where the reduzate has greater absorption, spectrophotometry can simply and rapidly determine the activity of glutamate dehydrogenase, or the content of NADH/NADPH.

Claim (Index 11):
A composition of Monosulfonic phenyltetrazole compounds comprising a general formula II: wherein: R 1  is substituent X 1  unsubstituted, or substituent X 1  substituted with one or more substitutable substituent X 2  independently, wherein substituent X 1  and/or substituent X 2  are selected optionally from the following substituted or unsubstituted groups: phenyl, nitro, sulfonic group, sulfonamide, a halogen, alkoxy, alkyl, 6-membered heterocycloalkyl group containing 1 or 2 N atoms, 5-membered heterocycloalkyl group containing 1 or 2 heteroatoms each independently selected from N, S, O, bicyclic heteroaryl groups containing 1 or 2 heteroatoms selected from N, S, O; R 2 , R 3  and R 4  are each independently selected from substituent Y or H, wherein substituent Y is optionally selected from the following groups: substituted or unsubstituted alkyl, alkoxy, nitro, halogen atom, azo, phenyl, substituted sulfonic group, heterocyclic alkyl containing 1 N substituent, cycloalkyl.
