Cholecalciferol, also known as Vitamin D3, is a fat-soluble vitamin that plays a crucial role in maintaining calcium and phosphorus balance in the body. It is synthesized in the skin upon exposure to sunlight and can also be obtained through diet and supplements. Cholecalciferol is essential for bone health, immune function, and overall well-being. Used in Pharmaceutical Industry: Cholecalciferol is used as a pharmaceutical ingredient for the prevention and treatment of vitamin D deficiency, rickets, and osteoporosis. It helps in maintaining healthy bones and teeth, promoting calcium absorption, and supporting immune function. Used in Dietary Supplements: Cholecalciferol is used as a dietary supplement to ensure adequate vitamin D intake, especially for individuals with limited sun exposure or those at risk of deficiency. It can be found in various forms, such as capsules, tablets, and liquid solutions. Used in Food Fortification: Cholecalciferol is used as a fortifying agent in various food products, such as milk, cereals, and orange juice, to enhance their nutritional value and contribute to the daily vitamin D requirements of consumers. Used in Analytical Chemistry: Cholecalciferol (6,19,19-d3) solution, also known as deuterated vitamin D3, is used as an internal analytical standard for the quantification of vitamin D3 concentration in dietary supplements, fortified foods, or within a complex biological matrix using LC-MS/MS. This helps in accurate measurement and quality control of vitamin D3 content in these products.
The CAS Registry Mumber 80666-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,6 and 6 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 80666-48: (7*8)+(6*0)+(5*6)+(4*6)+(3*6)+(2*4)+(1*8)=144 144 % 10 = 4 So 80666-48-4 is a valid CAS Registry Number.
