質量分析、非調和下方歪追跡-超球面探索と誘導体化反応による水道水生ぐさ臭原因物質の構造推定
A number of off-flavor events regarding tap water have occurred across Japan. Fishy smell is the second most common off-flavor in Japan. Its causative substance (hereafter referred to as FX) is still unrevealed to the best of our knowledge. The authors have found one of the causative substances and elucidated its structure partially, but not yet identified it. The number of the candidate structures of the FX was 46 at the moment. Therefore, the objective of this study is to narrow down the number of the candidate structures with mass spectrometry, quantum-chemical calculations (the anharmonic downward distortion following-scaled hypersphere search, ADDF-SHS), and a derivatization. The number of the candidate structures of the FX was narrow down to two from 46.
