Dibromomethane and bromochloromethane are preferred.
The process advantageously uses transition metal compounds as catalysts and the dibromomethane can be recovered.
Dibromomethane is used as a solvent, gauge fluid, and in organic synthesis.
This invention relates to an improved radiosynthesis of [18F]fluoromethyl bromide, whereby the distillation step has been improved to remove higher amounts of the dibromomethane radiolabeling precursor.
The use of dibromomethane is an improvement over the prior art which typically used HBr; a poisonous and ozone depleting gas.
