Description

General description

Sodium iodide is an inorganic salt. Mixture of chlorotrimethylsilane/sodium iodide in acetonitrile is a useful reagent for the cleavage of esters, lactones, carbamates and ethers.

Application

Sodium iodide may be used in the preparation of sodium hydroxide-sodium iodide reagent for the modified Winkler method for the determination of dissolved oxygen. It may be used for the synthesis of coppersensor-1 (CS1), a membrane-permeable fluorescent dye used for imaging labile copper pools in biological samples.

Caution

may contain black particle through the manufacture
