描述

一般說明

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.

應用

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.

注意

可能含有在生产过程中产生的黑色颗粒物
