Description

Sulphitocobalamin is a cobalt-containing coordination complex and a key derivative of Vitamin B12. This compound is valued for its stability and role as a precursor in the synthesis of various cobalamin-based pharmaceuticals and nutritional supplements. It is essential for manufacturers in the pharmaceutical, nutraceutical, and research sectors requiring a reliable source of high-purity cobalamin intermediates.

Application

• Pharmaceutical Intermediates: A critical starting material for the synthesis of active pharmaceutical ingredients (APIs) in Vitamin B12 injections and other parenteral formulations.
• Nutraceutical Manufacturing: Used in the production of high-grade dietary supplements and fortified foods to address Vitamin B12 deficiency.
• Biochemical Research: Serves as a standard and reagent in enzymatic studies, metabolic pathway analysis, and cobalt biochemistry research.
• Veterinary Medicine: Incorporated into animal feed supplements and veterinary injectables to promote livestock health and growth.
• Cell Culture Media: An essential component in specialized cell culture and fermentation media for biotechnology applications.
• Diagnostic Reagents: Utilized in the formulation of clinical diagnostic kits and assays for measuring Vitamin B12 levels.
