Description

22,23-Dihydroergosterol, Non-Irradiated is a high-purity sterol derivative, a key intermediate in the synthesis of vitamin D analogs and other bioactive compounds. Its non-irradiated status ensures the preservation of its native chemical structure, making it critical for research and development where defined molecular integrity is paramount. This product is essential for pharmaceutical R&D laboratories, nutraceutical manufacturers, and academic institutions focused on steroid chemistry, metabolic studies, and the development of new therapeutic agents.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of novel vitamin D2 (ergocalciferol) analogs and other sterol-based active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a standard or substrate in studies of sterol metabolism, membrane biophysics, and enzyme function related to cholesterol biosynthesis pathways.
• Nutraceutical Development: Serves as a starting material for the production of high-value, research-grade dietary supplements and functional food ingredients.
• Reference Standard: Employed in analytical laboratories for method development, calibration, and quality control of sterol-containing products via HPLC, GC, or LC-MS.
• Cosmeceutical R&D: Investigated for potential applications in topical formulations targeting skin barrier function and cellular signaling.
