Summary:To provide an analytical method of isopropylated phenylphosphate with high reliability.SOLUTION: An analytical method of isopropylated phenylphosphate includes the steps of: thermally extracting a specimen; obtaining mass spectrum of one or more compounds contained in the specimen by analyzing the thermally extracted specimen by gas chromatograph mass analysis method; and determining whether or not fragment ion or/and parent ion that is specific mass-to-charge ratio (m/z) are contained in mass spectrum.SELECTED DRAWING: Figure 1 【課題】実施形態は、信頼性の高いイソプロピル化フェニルホスフェートの分析方法を提供する。【解決手段】実施形態のイソプロピル化フェニルホスフェートの分析方法は、試料を熱抽出する工程と、熱抽出された試料をガスクロマトグラフ質量分析法で分析して試料に含まれる１以上の化合物のマススペクトルグラムを得る工程と、マススペクトルグラムに特定の質量電荷比（ｍ／ｚ）であるフラグメントイオン又は／及び親イオンが含まれるかどうかを判定する工程と、を有する。【選択図】 図１
