Description

Thiamine Bromide CAS NO 7019-71-8 is a quaternary ammonium salt derivative of vitamin B1 (thiamine), widely recognized for its role as a key pharmaceutical intermediate. This compound is essential for the synthesis of more complex thiamine-based active pharmaceutical ingredients (APIs) and fine chemicals. It is primarily utilized by manufacturers in the pharmaceutical, nutraceutical, and research sectors requiring high-purity building blocks for therapeutic and nutritional applications.

Application

• Pharmaceutical Synthesis: A crucial intermediate in the production of thiamine hydrochloride and other vitamin B1 derivatives used in medications and supplements.
• Nutraceutical Manufacturing: Serves as a precursor in the formulation of high-grade vitamin B-complex nutritional products.
• Biochemical Research: Used as a standard or reagent in enzymatic studies and metabolic pathway research related to thiamine function.
• Veterinary Pharmaceuticals: Employed in the development of vitamin supplements and treatments for animal health.
• Fine Chemical Production: Acts as a building block for synthesizing specialized organic compounds in advanced chemical manufacturing.
