DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Section cross-reference(s): 4 The purity of governor-designated drugs (2,5-dimethoxy-4-iodophenethylamine (2C-I), N-methyl-a-ethyl-3,4-methylenedioxypenethylaine (MBDB), 3-[2-(isopropylmethylamino)ethyl]-5-methoxyindole (5-MeO-MIPT), and 3-chlorophenylpiperazine (3CPP)) used for the purpose of living body influence evaluation was measured. The samples were analyzed by using TLC, GC-FID, IC, HPLC, and NMR. Using TLC and GC-FID methods, only one main spot and a single peak was detected in all samples. Using IC, the form of existence of all compds. was clarified, and using HPLC-PDA and NMR methods, the purity of all samples was calcd. 135795-90-3 and 2905-56-8 are just another two chemicals used in this study. with to be over 90%. .
