### MDMA Isomer Research Set (R & S)

Our MDMA Isomer Research Set provides researchers with separate enantiomers of MDMA for advanced stereochemistry and pharmacological studies. Each enantiomer is isolated to 99% enantiomeric excess (ee) purity.

**Set Includes:**
- **2g R(-)-MDMA** (less active enantiomer)
- **2g S(+)-MDMA** (highly active empathogenic enantiomer)
- **Enantiomeric Purity:** 99% ee for each
- **Form:** White crystalline powder (HCl salts)

**Research Applications:**
- Stereochemistry studies
- Enantioselective pharmacology research
- Receptor binding specificity studies
- Metabolic pathway research
- Comparative efficacy studies

**Analytical Data Provided:**
- Chiral HPLC chromatograms
- Optical rotation measurements
- Mass spectrometry confirmation
- NMR spectral data
- Purity certificates

**Physical Properties:**
- R(-)-MDMA: [α]D = -45° to -48°
- S(+)-MDMA: [α]D = +45° to +48°
- Both forms: Freely soluble in water and organic solvents

**Storage:**
- Store at room temperature
- Protect from light and moisture
- Keep in original sealed containers
- Stable for 2+ years

This research set enables scientists to study the distinct pharmacological profiles of MDMA's enantiomers with the highest purity standards.
