1200-22-2 - Definition:

(R)-α-Lipoic Acid (CAS: 1200-22-2) is the (R)-enantiomer of Lipoic Acid. A vitamin-like, C8 thia fatty acid with anti-oxidant properties. It has a role as a prosthetic group, a nutraceutical and a cofactor. It is a lipoic acid, a member of dithiolanes, a heterocyclic fatty acid and a thia fatty acid. It is functionally related to an octanoic acid. It is a conjugate acid of a (R)-Lipoate. It is an enantiomer of a (S)-Lipoic Acid.

1200-22-2 - Application:

(R)-α-Lipoic Acid (CAS: 1200-22-2) is a biological antioxidant with prooxidant activities.
(R)-α-Lipoic Acid is a vitamin-like coenzyme that exists in mitochondria. It is involved in aerobic metabolism to produce energy and is a powerful antioxidant. Its antioxidant capacity is 400 times that of vitamin C, and it is both water and fat-soluble. Benefits: Higher biological activity; Enzyme catalysis technology; More stable Lower level of toluene.
(R)-α-Lipoic Acid is an antioxidant, which is an essential cofactor of mitochondrial enzyme complexes. (R)-(+)-α-Lipoic acid is more effective than racemic Lipoic acid.
Food industry: used in dairy foods, meat foods, baked foods, pasta foods, various beverages, candies, flavored foods, etc.
Medical Manufacturing: health food, base materials, fillers, biological drugs, pharmaceutical raw materials, etc.
Used for diabetic neuropathy complication medicine and dietary supplement。
Vitamin drugs, the effect is better than lipoic acid.
