Ningbo Inno Pharmchem Co., Ltd. specializes in providing high-quality chemical compounds, and Vitamin D3, or Cholecalciferol, is a cornerstone of our product line. Understanding its chemical properties and production methods is essential for its effective use in various applications, from pharmaceuticals to nutritional supplements.

Cholecalciferol (CAS 67-97-0) is a secosteroid, a type of steroid molecule with one of its rings opened. It typically appears as a white to off-white crystalline powder. Its stability is a critical consideration; it is sensitive to air, heat, and light. This means that proper storage and handling are crucial to maintain its potency. Solutions of Cholecalciferol, especially without antioxidants, can be unstable and are best used immediately after preparation. Researchers often investigate the precise Vitamin D3 chemical properties to optimize formulation stability.

Industrially, Vitamin D3 is often produced from lanolin, a wool wax byproduct. The process involves several steps, starting with cholesterol extracted from the wool grease. This cholesterol is converted into 7-dehydrocholesterol, which is then irradiated with ultraviolet light. This photochemical reaction opens the B-ring of the sterol, producing previtamin D3, which then isomerizes to Vitamin D3. The careful control of these processes is key to achieving high purity.

The Vitamin D3 synthesis and activation pathway continues after production. In the body, it is converted into its active hormonal form, calcitriol, through enzymatic hydroxylation in the liver and kidneys. This active form is vital for calcium and phosphorus metabolism, directly impacting bone health and immune system function. For applications requiring high purity, sourcing high purity Vitamin D3 powder is paramount.

Ningbo Inno Pharmchem is committed to supplying Cholecalciferol that meets the highest standards. Whether you are looking to buy Vitamin D3 online for research, pharmaceutical development, or nutritional product manufacturing, our products are processed to ensure quality and reliability. Our understanding of the Vitamin D3 health benefits and its role as a Cholecalciferol pharmaceutical intermediate drives our dedication to excellence.
