VITAMIN D4(CAS: 511-28-4)

Vitamin D3 (CAS: 511-28-4) is a white, crystalline solid with a molecular weight of approximately 391.65 g/mol. It has a solubility of up to 0.125 g/L in water and is highly soluble in organic solvents like chloroform and ethyl acetate. Vitamin D3 is relatively stable under normal storage conditions but can undergo hydrolysis and photodegradation. It does not readily react with most metals but can undergo oxidation in the presence of air and light.

Vitamin D3 (CAS: 511-28-4) is typically synthesized through the photolysis of 7-dehydrocholesterol in the presence of ultraviolet light, which is a natural process in the skin. For industrial production, synthetic methods involve the conversion of 7-dehydrocholesterol to Vitamin D3 using UV light, followed by chemical modification and purification steps. The process often uses a catalyst like nickel to enhance the conversion efficiency.

Vitamin D3 (CAS: 511-28-4) is widely used in the pharmaceutical industry for the treatment of osteoporosis and rickets. It is also utilized in the food industry as a dietary supplement and fortification agent. Additionally, it is applied in the cosmetic industry for its skin health benefits. In research, it is used in the development of sensors and semiconductors due to its photochemical properties.

When handling Vitamin D3 (CAS: 511-28-4), it is important to use appropriate personal protective equipment (PPE) such as gloves and goggles. Work should be conducted in a well-ventilated area or fume hood to avoid inhalation of dust. Spills should be cleaned up immediately using appropriate absorbents, and the area should be thoroughly washed down. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage instructions to ensure safe laboratory practices.
