Product Information

• Name: 2-Pyridine selenyl bromide
• Brand: Biosynth
• Description: 2-Pyridine selenyl bromide is a co-precursor for the synthesis of 2-selenides. It can be prepared by reacting 2-pyridinesulfonyl chloride with sodium periodate in acetonitrile. This compound can then be converted to a 2-selenide by treatment with methanol and periodic acid. The analytical and preparative methods are shown below:Analytical: Dissolve the sample in dichloromethane, add triethylamine, and extract into diethyl ether. Add a small amount of potassium bromide to the organic layer and evaporate to dryness under vacuum. Recrystallize from acetonitrile.Methanolysis: Dissolve the sample in methanol, add a catalytic amount of hydrochloric acid, and heat at reflux for 12 hours. Cool the solution, filter off any insoluble material, evaporate to dryness
