To provide an aromatic sulfide compound purification method and production method; a derivative production method using the compound obtained by the purification method; and the derivative or the like.SOLUTION: An aromatic sulfide compound purification method includes (a) a step in which a mixture containing an aromatic sulfide compound represented by the formula (1) and impurities is added to a good solvent of the aromatic sulfide compound to precipitate the insoluble components, creating a treatment solution; (b) (b-1) a step for using a filter material that includes a layer containing a filtration aid to filter the treatment liquid, producing a filtrate, (b-2) a step for adding the filtration aid to the treatment liquid and then filtering it, thus forming the filtrate, or (b-3) a step for performing both (b-1) and (b-2), thus yielding the filtrate; and (c) a step for adding the filtrate to a poor solvent of the aromatic sulfide compound to crystallize it, thus creating the aromatic sulfide compound.SELECTED DRAWING: None 【課題】芳香族スルフィド化合物の精製方法及び製造方法、かかる精製方法によって得られた該化合物を用いた誘導体の製造方法、並びに該誘導体等を提供する。【解決手段】（ａ）式（１）で表される芳香族スルフィド化合物と不純物とを含有する混合物を、芳香族スルフィド化合物の良溶媒に加え不溶解成分を析出させて処理液を得る工程と；（ｂ）（ｂ－１）ろ過助剤を含む層を有するろ材を用い処理液をろ過して、ろ液を得る工程、（ｂ－２）ろ過助剤を処理液に加えた後、ろ過することによって、ろ液を得る工程、又は（ｂ－３）（ｂ－１）及び（ｂ－２）の両方を行い、ろ液を得る工程と；（ｃ）ろ液を、芳香族スルフィド化合物の貧溶媒に加えて晶析させることによって、芳香族スルフィド化合物を得る工程と；を含む芳香族スルフィド化合物の精製方法を提供する。JPEG2024076883000020.jpg42161【選択図】なし
