Properties and stability


Storage method

This product should be sealed and stored in a dry place at 4°C away from light.

Synthesis method

1. There are many production methods. Starting from propargyl alcohol, through oxidation; esterification, and then cyclization with 2- aminooxazoline nucleoside, can be obtained 2,2-oxo-pyrimidine nucleoside is then acylated, brominated, catalytically hydrogenated, and hydrolyzed to obtain iodine glycoside. 5′- deoxycytosine nucleotides can be prepared from fish essence, and iodine glycosides can also be prepared after further processing.



1. Used for biochemical research. Tracheitis virus testing. Treat herpes simplex keratitis.
