      Abstract
      Abstrak. Telah berhasil disintesis turunan pyrazolone yaitu 4-dodecandioylbis(1-phenyl-3-methyl-5- pyrazolone) atau (H2DdBP) dengan metode Jensen, melalui reaksi 1-phenyl-3-methyl-5-pyrazolone dan dodecandioyl chloride dalam suasana basa. Senyawa yang dihasilkan dalam bentuk keto dengan titik leleh 148-1520C, puncak vibrasi 3451 (br, OH), 1624 (s, C=O), 1589 (s, phenyl C=C), 1558 (s, pyrazolone ring). Pergeseran kimia untuk 1H-NMR adalah 7.81–7.84, 7.43–7.46, 7.26–7.290 (m, 10H, Ph; 2.72–2.75 (t,4H, (CH2)2); 2.47 (s, 6H, CH3); 1.71–1.76 (m, 4H, (CH2)2); 1.32 (m, 12H, (CH2)6)
