R-Alpha Lipoic Acid (R-ALA, CAS 1200-22-2) is the naturally occurring, biologically active enantiomer of alpha lipoic acid. Unlike the synthetic racemic mixture, R-ALA is the form the body recognizes and utilizes — offering superior antioxidant and metabolic-support activity at lower doses.
Physical & Chemical Properties
- CAS number: 1200-22-2
- Appearance: pale yellow crystalline powder
- Solubility: slightly soluble in water; soluble in ethanol and oils
- Molecular formula: C8H14O2S2
- Molecular weight: 206.33
- Enantiomeric purity: R-form ≥98% (chiral HPLC)
- Purity: ≥98%
Key Benefits for Formulation
- Bioactive enantiomer: the natural R-form, not synthetic racemate
- Superior bioavailability: effectively utilized at lower doses
- Antioxidant recycling: regenerates vitamins C & E, glutathione
- Metabolic support: glucose & energy metabolism cofactor
- Clean profile: no S-form (which can interfere with uptake)
Main Applications
- Antioxidant supplements: premium free-radical defense
- Metabolic health: glucose-support & insulin-sensitivity formulas
- Anti-aging: mitochondrial support products
- Neuropathy support: nerve-health applications
- Sports nutrition: recovery & energy metabolism
