What is Thionyl bromide ?

Chemical properties

orange-yellow liquid; slowly decomposes on standing; prepared by reaction of SOCl2 and HBr [MER06]

The Uses of Thionyl bromide

Thionyl Bromide is used in the preparation of carbon nanotube-phosphorylcholine polymer composite used in blood condition.

The Uses of Thionyl bromide

Thionyl bromide
To a solution of the SM (2.63 g, 12.5 mmol) in DCM (60 mL) at 0 C was added DMF (0.49 mL, 6.3 mmol) followed by SOBr2 (1.26 mL, 16.3 mmol). The mixture was allowed to warm to RT and stir for 14 h. Cold ether (30 mL) was added and the mixture was cooled to 0 C, causing solids to precipitate out of solution. The solids were collected by filtration and dried on the filter pad to provide the product as an off-white solid. [3.31 g]
