Description

Vitamin D3 Sulfoconjugate is a biologically significant metabolite of cholecalciferol, formed through sulfation at the 3β-hydroxyl position. This water-soluble conjugate plays a crucial role in the transport, regulation, and metabolic pathways of vitamin D within the body. It is primarily utilized by research institutions and manufacturers in the pharmaceutical and nutraceutical sectors for advanced metabolic studies and the development of specialized therapeutic and diagnostic agents.

Application

• Pharmaceutical Reference Standard: Serves as a critical analytical standard for the quantification and qualification of vitamin D metabolites in drug development and quality control.
• Biochemical Research: Used in studies investigating vitamin D metabolism, sulfotransferase enzyme activity, and the role of sulfated steroids in cellular signaling.
• Nutraceutical Formulation: Incorporated into advanced dietary supplements targeting specific metabolic pathways, leveraging its improved water solubility profile.
• Diagnostic Kit Development: Acts as a key antigen or calibrator in the production of immunoassay kits for measuring vitamin D status and related metabolic disorders.
• Metabolite Synthesis Intermediate: Used as a precursor or intermediate in the chemical or enzymatic synthesis of other vitamin D analogs and conjugates.
