Zusammenfassung:	To provide a method for improving storage stability of a precursor compound of a radioactive fluorine-labeled compound.SOLUTION: Solution in which a precursor compound expressed by the following formula (2) or salt thereof is stored in a dissolved state into organic solvent. [in the formula, X1 denotes hydrogen atom or halogen atom, X2 denotes fluorine atom or nitrile group, R1 denotes substituted or unsubstituted alkylsulfonyloxy group, or substituted or unsubstituted arylsulfonyloxy group].SELECTED DRAWING: None 【課題】放射性フッ素標識化合物の前駆体化合物の保存安定性を向上させる方法の提供。【解決手段】下記式（２）で表される前駆体化合物又はその塩を、有機溶媒に溶解した状態で保存した溶液を提供する。〔式中、Ｘ１は水素原子又はハロゲン原子を示し、Ｘ２はフッ素原子又はニトリル基を示し、Ｒ１は置換若しくは非置換アルキルスルホニルオキシ基、又は、置換若しくは非置換アリールスルホニルオキシ基を示す。〕【選択図】なし
