Thiamine nitrate is the nitrate salt form of thiamine (vitamin B1), a water-soluble vitamin essential for carbohydrate metabolism and neural function. It is produced synthetically and supplied as a white to off-white crystalline powder with a characteristic faint odor. Unlike thiamine hydrochloride, the nitrate salt is less hygroscopic and exhibits greater stability in dry blends, making it a preferred choice for certain solid dosage forms and food fortification.
As a vitamin B1 source, thiamine nitrate is widely used in pharmaceutical preparations, dietary supplements, and food enrichment. It plays a critical role in energy production as a coenzyme in the citric acid cycle and pentose phosphate pathway. The nitrate form is particularly valued in multivitamin tablets and premixes where moisture sensitivity is a concern.
