Thiamine mononitrate, also known as Vitamin B1 Nitrate, is a nitrate derivative of vitamin B1. It appears as white to pale yellow crystalline powder or crystals, slightly soluble in water and barely soluble in ethanol and chloroform, with excellent ambient air stability.
Compared with thiamine hydrochloride, it features lower water solubility yet superior stability under alkaline conditions. Widely adopted as a food fortificant, it is added into staple grains, flour, pastries and soy sauce; it also sees extensive application in pharmaceutical manufacturing.
Thiamine mononitrate plays an essential role in carbohydrate metabolism and helps support the body’s natural energy production.
Applied in dietary supplements, fortified foods, and daily wellness products.
Free samples available, with complete COA, TDS and MSDS documents supplied.
