Description
DL-ALPHA-TOCOPHEROL ACETATE, also known as Tocopheryl Acetate or Vitamin E Acetate, is a natural form of Vitamin E that serves as a fortifying agent and dietary supplement. It is a clear light yellow to light green viscous liquid, and its richest sources include green vegetables, grains, and oils, particularly palm, safflower, and sunflower oils. DL-ALPHA-TOCOPHEROL ACETATE is widely used in various industries due to its antioxidant properties and health benefits.
Uses
Used in Food Industry:
DL-ALPHA-TOCOPHEROL ACETATE is used as an antioxidant for preserving the quality and freshness of vegetable oils and shortening. It helps in preventing rancidity and extending the shelf life of these products.
Used in Pharmaceutical Industry:
DL-ALPHA-TOCOPHEROL ACETATE is used as an internal standard for High-Performance Liquid Chromatography (HPLC) or Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) Vitamin E testing applications. It is essential for quality control testing of Vitamin E fortified foods, dietary supplements, or pharmaceuticals.
Used in Skin Care and Dermatological Industry:
DL-ALPHA-TOCOPHEROL ACETATE is used as a key ingredient in skin care products and dermatological preparations. It is known for its antioxidant properties, which help in protecting the skin from environmental damage and promoting overall skin health.
Used in Analytical Chemistry:
DL-ALPHA-TOCOPHEROL ACETATE may be used as an analytical standard for the determination of the analyte in aquatic organisms, fish feed, and pharmaceutical formulations by colorimetric and chromatography techniques.
Used in Therapeutic Applications:
DL-ALPHA-TOCOPHEROL ACETATE, in combination with α-tocopherol, has been used in the therapy of various conditions such as sterility, muscular dystrophy, cardiac vascular disorders, and anemia. Its antioxidant properties contribute to its effectiveness in these treatments.
Check Digit Verification of cas no
The CAS Registry Mumber 52225-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,2,2 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 52225-20:
(7*5)+(6*2)+(5*2)+(4*2)+(3*5)+(2*2)+(1*0)=84
84 % 10 = 4
So 52225-20-4 is a valid CAS Registry Number.
