Description

Thiamine hydrochloride (CAS 67-03-8 ), also known by its FEMA 3322 designation, is the stable salt form of vitamin B1 used across pharmaceutical, food, and cosmetic manufacturing. It functions as a nutritional fortifier and process stabilizer, enabling manufacturers to deliver consistent B1 potency in finished products. In pharmaceutical manufacturing, it is the preferred active ingredient. This compound is used in oral tablets, injectables, and multivitamin formulations due to its high water solubility and stable shelf life. Food and beverage producers use it to fortify breakfast cereals and flour. It is also essential for infant formula and energy drinks to meet regulatory nutritional labeling requirements. In flavor applications, it serves as a precursor in Maillard reaction systems. This process generates meat-like and savory flavor profiles in processed food production. Personal care formulators incorporate it into scalp treatments and hair care products targeting enrichment claims. Thiamine hydrochloride is supplied as a white crystalline powder in packaging ranging from kilogram bags to bulk metric ton quantities. It is available in USP , BP , and Ph. Eur. specifications. These grades meet the compliance requirements of different regulated markets. FCC -grade material is standard for food and beverage fortification applications to ensure high safety standards.
