Anwendungen

2-Nitrophenylselenocyanate is used to study the mechanism of its reaction with the zinc/thiolate clusters of metallothionein. It is also used in the preparation of 2,3-seco-5 alfa-cholestane-2,3-diol and in the preparation of 4alfa-methyl-2,3-seco-5 alfa-cholestane-2,3-diol. Further, it is used in the preparation of 2-nitrophenylselenyl derivative and 3alfa-[(2-Nitrophenyl)seleno]androsta-1,5-dien-17beta-ol. In addition to this, it reacts with 6-bromo-hexanoic acid methyl ester to get 6-(2-nitro-phenylselanyl)-hexanoic acid methyl ester.

Bemerkungen
