Pharmaceutical Materials

Benfotiamine, a lipid-soluble derivative of vitamin B1 (thiamine), is recognized for its enhanced bioavailability and therapeutic potential in managing diabetic complications and neurological disorders. With a CAS number of 22457-89-2, it exhibits a molecular formula of C₁₉H₂₃N₄O₆PS and a molecular weight of 466.45 g/mol. Its white crystalline powder form and melting point of approximately 200°C highlight its stability. Benfotiamine surpasses water-soluble thiamine in bioavailability, achieving up to 3.6 times higher absorption and a fivefold increase in blood concentration. It acts by inhibiting advanced glycation end-product (AGE) formation and stimulating transketolase activity, thereby reducing oxidative stress and inflammation. Clinically, it is used to prevent diabetic neuropathy, retinopathy, and cardiovascular complications, while also showing efficacy in treating neuropathic pain and HIV-related conditions. Its safety profile supports long-term use, making it a valuable therapeutic agent.

Usage： Benfotiamine is a fat-soluble thiamine (vitamin B1) derivative. After entering the body, it can be converted into physiologically active vitamin B1. It is mainly used for the treatment of diabetic complications, especially for the treatment and prevention of diabetic retinopathy.

Packaging and Shipping： 25KG/drum or as per buyer requirements.

Storage: Store in a cool place. Keep container airtight and store in a dry and ventilated place.
