Iodonitrotetrazolium Specification

Iodonitrotetrazolium, with the CAS NO.146-68-9, its synonyms are 2-(p-Iodophenyl)-3-(p-nitrophenyl)-5-phenyltetrazolium
chloride; Iodonitrotetrazolium chloride; Iodonitrotetrazolium purple; Iodonitrotetrazolium violet; 2-(4-Iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride; 2-(p-Iodophenyl)-3-(p-nitrophenyl)-5-(phenyl)-2H-tetrazolium; 2H-Tetrazolium, 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyl-, chloride. Iodonitrotetraolium is an artificial electron acceptor which can be utilized in a colorimetric assay to determine the concentration of protein in a solution. It can be reduced by succinate dyhydrogenase to Forazan.

Physical properties about Iodonitrotetrazolium are: (1)ACD/LogP: 3.278; (2)ACD/LogD (pH 5.5): 3.28; (3)ACD/LogD (pH 7.4): 3.28; (4)ACD/BCF (pH 5.5): 182.60; (5)ACD/BCF (pH 7.4): 182.60; (6)ACD/KOC (pH 5.5): 1446.74; (7)ACD/KOC (pH 7.4): 1446.74; (8)#H bond acceptors: 7; (9)#Freely Rotating Bonds: 4;

When you are using this chemical, please be cautious about it as the following:
1. Wear suitable protective clothing and gloves;
