About Lipoic Acid

Vaqora Chemicals supplies Lipoic Acid, a high-purity reference standard of Thioctic acid registered under CAS number 1200-22-2. With the molecular formula C8H13O2S2-, it has a molar mass of 205.3 g/mol. The IUPAC name is 5-[(3R)-dithiolan-3-yl]pentanoate. It is also known as (R)-(+)-α-Lipoic acid or (R)-lipoate.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Thioctic acid standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. It is used across pharmaceutical manufacturing and academic and industrial research.

We offer Lipoic Acid in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
