| abstract |
The invention comprises a solid precursor and a solid precursor formed by an organic salt, as well as a preparation method and application thereof. In the solid precursor of the present invention, the process of separately purifying [18F] fluoride using a filter can be omitted, and the use of the phase transfer catalyst in excess can be avoided, and the residual substance after the reaction in the solid support precursor can be easily removed. When the solid precursor of the present invention is filled into a filter to be used, the entire process of [18F] fluorination can be carried out in an all-in-one system, which is very suitable for automated synthesis equipment. |
