Description
Alpha Lipoic Acid Product Overview
Alpha lipoic acid (C8H14O2S2) is a pale yellow crystalline powder with a characteristic odor. It contains a five-membered ring with a disulfide bond and melts at about 60–62°C. The standard commercial form is the racemic mixture; the natural R-enantiomer (R-ALA, CAS 1200-22-2) is available as a separate grade.
Producers of nutritional products use it in tablets and capsules, where regulations in each market govern the claims allowed. Pharmaceutical companies use thioctic acid as an API in tablets and infusions in several countries, and the same substance is also listed as Thioctic acid. Cosmetic formulators use it as an antioxidant ingredient in skin care.
Because it melts at a low temperature and can polymerize when heated, it needs careful handling during granulation and storage in a cool place. For other ingredients often used alongside it, see Coenzyme Q10 and L Carnitine.

Frequently Asked Questions
What is the difference between racemic ALA and R-ALA?
Racemic alpha lipoic acid contains equal amounts of the R- and S-forms. R-ALA is the naturally occurring enantiomer and is offered as a separate, higher-priced grade.
Is alpha lipoic acid the same as thioctic acid?
Yes. Thioctic acid is the pharmacopoeia name for the same substance.
How can I get a price and documents?
Prices depend on quantity, packaging and destination. Contact us with your required volume to receive a quotation together with the CoA and SDS.
