Application

3,5-Dichloro-2-hydroxybenzenesulfonyl chloride was used in the synthesis of (1R,2R)-(+)-1,2-(3,3′,5,5′-tetrachloro-2,2′-dihydroxydibenzenesulfonamido)-1,2-diphenylethane and (1R,2R)-(+)- 1,2-(3,3′,5,5′-tetrachloro-2,2′-dihydroxydibenzenesulfonamido)cyclohexane. It was used as chromogenic system in one-step kinetic method for the determination of 5′-nucleotidase.

We describe a one-step kinetic method for the determination of 5'-nucleotidase (EC 3.1.3.5). Inosine is formed by the hydrolysis of inosine 5'-monophosphate which is catalyzed by seric 5'-nucleotidase, and then is converted to hypoxanthine by nucleoside phosphorylase. Two moles of
