How to use

In Vitro:

The AV-105 synthesis method utilizes a primary tosylate instead of a primary mesylate as an active leaving group. Use of the tosylate precursor for radiofluorination is beneficial, at least for the reason that the tosylate generated during the radiofluorination reaction is readily removed by chromatographic means from the 18F-radiolabeled imaging product.
