Thermal analysis techniques have been applied to study the thermal behavior of fenbendazole (Fen) and rafoxanide (Raf). Semi-empirical molecular orbital calculations were used to confirm these results.
Fen is chemically named as methyl [5-(phenylsulfanyl)-1H-benzoimidazol-2-yl] carbamate.1 It is a benzimidazole carbamate anthelmintic utilized in veterinary medicine as antiparasitic drug.2
The thermal behavior of Fen and Raf was studied as the first trial in this work using different thermal analysis techniques. The results were confirmed using MO calculations to obtain the correct path way of thermal decomposition of these drugs.
