“…Phosmet was extracted from Imidan [52% Phosmet (w/w), Siegfried Agro, Zofingen, Switzerland) with acetone in a Soxhlet apparatus and, after evaporation under reduced pressure, recrystallized from methanol twice before use. Spectroscopic properties [MS (ESI+), m / z 318 ([M + H] + ); 1 H NMR (DMSO) δ 3.67 (6H, d, CH 3 ), 4.96 (2H, d, CH 2 ), 7.95−7.86 (4H, m, Ar−H); 13 C NMR (DMSO) δ 54.32 (d, CH 3 ), 39.05 (d, CH 2 ), 123.80, 131.55, 135.23 (s, Ar−C), 166.39 (s, CO); IR (ATR) (cm -1 ) 3481, 3025, 2995, 2949, 2867, 1780, 1719, 1612, 1463, 1452, 1406, 1376, 1304, 1279, 1188, 1082, 1072, 914, 831, 819, 797, 722, 692, 676] and melting point of the obtained colorless crystals corresponded to the expected structure and data given in refs (melting point) and 15 (IR spectra). The purity of the recrystallized phosmet was determined by HPLC to be >99% (UV, 220 nm).…”
