Thioctic Acid

Thioctic Acid (alpha-lipoic acid) is a naturally occurring dithiolane compound that functions as a redox-active enzyme cofactor and potent antioxidant, used therapeutically for diabetic peripheral neuropathy and as a widely sold antioxidant supplement. Simson Pharma's Thioctic Acid reference standard and impurities support compendial and stability-indicating testing across these applications.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Thioctic Acid Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
