Synthetic Cathinone vs. Fluorinated Amphetamines – A scientific overview
Research into new psychoactive substances (NPS) includes numerous chemical classes with different structural properties. Two frequently studied groups are Synthetic cathinones and fluorinated amphetamines. Although both classes have structural similarities, they differ in their chemical composition, their analytical characteristics and their research applications.
This article provides an objective overview of both classes of substances from a scientific perspective.
What are synthetic cathinones?
Synthetic cathinones are β-keto derivatives of the amphetamines. Characteristic is an additional keto group which influences the chemical properties of the molecules.
Known representatives are, for example:
- 3-MMC
- 4-MMC
- 3-CMC
- 4-CMC
These compounds are mainly investigated in analytical, toxicological and forensic studies.
What are fluorinated amphetamines?
Fluorinated amphetamines also belong to the group of amphetamine derivatives. In these, a hydrogen atom of the aromatic ring was replaced by fluorine.
The scientifically described representatives include:
- 2-FA
- 3-FA
- 4-FA
These compounds are regularly used as reference materials in laboratories.
Chemical comparison
