Manufacturer Vitamin D3 CAS 67-97-0
Vitamin D3 Description
Vitamin D3 (CAS 67-97-0, C ₂₇ H ₄₄ O, MW 384.64) is a fat-soluble secosteroid derived from cholesterol. It is the biologically energetic type of Vitamin D produced in the skin upon direct exposure to UVB radiation (290– 315 nm). The compound appears as white to beige crystalline powder with a melting point of 83– 86 ° C. It is soluble in ethanol, acetone, chloroform, and vegetable oils yet practically insoluble in water.
Vitamin D3 is one of the most powerful form of Vitamin D, substantially a lot more effective than Vitamin D2 (ergocalciferol) in maintaining the body’s Vitamin D status. It is at risk to isomerization under UV light and oxidation in the existence of light, warm, and oxygen, needing cautious handling and storage space.
