The present invention relates to a precursor of positron emission tomography (PET) radioactive medical supplies, a preparation method thereof, and an application thereof, and more specifically, to a precursor having a tetravalent organic salt leaving group, a preparation method, and a method for preparing desired PET radioactive medical supplies in a high radiochemical yield within a short preparation time by introducing
18
F using the same through a single step. The precursor having a tetravalent organic salt leaving group of the present invention can simplify the known complex multistep preparation of radioactive medical supplies into a single step, can save production costs because an excessive amount of a phase transfer catalyst is not required, facilitates separation of a compound after reaction, and enables rapid reaction velocity. The features are appropriate for the mass production of PET radioactive medical supplies by an automated synthesis system.

Anisole and fluoroanisoles display distinct conformational preferences, as evident from a survey of their crystal structures. In addition to altering the free ligand conformation, various degrees of fluorination have a strong impact on physicochemical and pharmacokinetic properties. Analysis of anisole and fluoroanisole matched molecular pairs in the Pfizer corporate database reveals interesting trends:
