Thioctic Acid
USP/EP-grade Thioctic Acid (alpha-lipoic acid, CAS 1077-28-7), 99–101%, supplied wholesale by Zyntex to licensed producers. Pharmaceutical API for film-coated tablets and intravenous infusion solutions. CoA and SDS.
Description
Thioctic Acid Product Overview
Thioctic acid (C8H14O2S2) is a light yellow crystalline powder that melts at about 60–62°C. It is the racemic mixture of R- and S-lipoic acid and contains a five-membered ring with a disulfide bond, which makes it sensitive to heat and light.
In addition, pharmaceutical companies in several European and Asian countries use it as a prescription API in film-coated tablets and, as salts with trometamol or meglumine, in solutions for intravenous infusion. Because of its low melting point and tendency to polymerize, producers keep process temperatures low. The same substance also appears in nutritional products under the name Alpha Lipoic Acid.
Notably, Zyntex supplies pharmacopoeia-grade thioctic acid only to licensed pharmaceutical companies. Related APIs in our range also include Benfotiamine and Vitamin B6 (Pyridoxine HCl).

⚠️ Safety & Handling: Harmful if swallowed in concentrated form and may cause skin and eye irritation. Avoid dust formation and also wear gloves and eye protection. Store in tightly closed, light-resistant containers below 25°C, because it melts at a low temperature and can polymerize. Always consult the Safety Data Sheet (SDS), because it contains the full classification and handling instructions.
Frequently Asked Questions
Is it the same as alpha-lipoic acid?
Yes. Thioctic acid is the pharmacopoeia name, whereas alpha-lipoic acid is the common name in nutritional products.
Why must it be stored cool?
Because it melts at about 60°C and can polymerize when heated, cool storage keeps it stable.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
