Description

R(-)-Amphetamine Sulfate (Levamphetamine Sulfate) is the levorotatory enantiomer of amphetamine sulfate, a potent central nervous system stimulant. This specific stereoisomer is of significant interest in pharmaceutical research and development due to its distinct pharmacological profile compared to its dextrorotatory counterpart. It is primarily utilized by research institutions and pharmaceutical companies engaged in neuroscience, analytical method development, and the synthesis of specialized reference standards.

Application

• Pharmaceutical Reference Standard: Serves as a certified standard for quality control and analytical method validation in drug testing and forensic analysis.
• Neuroscience Research: Used in preclinical studies to investigate the mechanisms of action, metabolism, and stereoselective effects of amphetamine derivatives on neurotransmitter systems.
• Metabolite Synthesis: Acts as a key intermediate or precursor in the synthesis of specific metabolites for pharmacokinetic and toxicological studies.
• Analytical Chemistry: Employed as a calibration standard in chromatographic (HPLC, GC) and spectroscopic techniques to ensure accurate quantification.
• Pharmacological Profiling: Utilized in vitro and in vivo assays to study adrenergic and dopaminergic receptor interactions and stereochemical selectivity.
