Description

2-(3-Hydroxypropoxy)-1,25-Dihydroxyvitamin D3 is a synthetic analog of the active form of Vitamin D, specifically engineered for enhanced biological activity and stability. This compound is critical for research and development in the pharmaceutical and nutraceutical sectors, where precise control over calcium metabolism and cell differentiation is required. It is primarily utilized by manufacturers of advanced therapeutic agents and high-purity dietary supplements targeting bone health and immune system modulation.

Application

• Pharmaceutical Active Ingredient: Key intermediate or active component in prescription medications for treating osteoporosis, psoriasis, and secondary hyperparathyroidism.
• Nutraceutical Formulations: Used in high-end dietary supplements aimed at supporting bone density, calcium absorption, and immune function.
• Biochemical Research: Essential tool in life science research for studying Vitamin D receptor (VDR) pathways, gene expression, and cell proliferation mechanisms.
• Veterinary Medicine: Incorporated into specialized feeds or treatments for metabolic bone disorders in livestock and companion animals.
• Cosmeceutical Development: Investigated for use in topical formulations targeting skin cell regulation and renewal.
