Article Synopsis
- Identification of specific impurities in (S)-(+)-methamphetamine can aid criminal investigations related to its abuse.
- Two well-known impurities, (1S,2S)-(+)-chloropseudoephedrine and (1R,2S)-(-)-chloroephedrine, result from particular synthesis methods involving ephedrine compounds.
- A new impurity, (1S,2S)-1-methylamino-1-phenyl-2-chloropropane, is linked to the metal-catalyzed synthesis process and can be formed through reactions involving certain chemical derivatives.

Impurity profiling and classification of seized methamphetamine may play an important role in the interpretation of analytical results, the determination of the synthetic method employed, and the criminal investigations of drug traffic routes. Our study is focused on classifying seized methamphetamine samples according to the groups sorted by the types and quantities of impurities present in illicit methamphetamine samples. The samples (100mg) were dissolved in 2 mL of potassium phosphate buffer (pH 7.
