Uses
Used in Food Industry:Sudan IV is used as a colorant in the food industry for coloring waxes, oils, and varnishes. Its vibrant red hue adds visual appeal to these products, enhancing their appearance and consumer appeal.
Used in Biological Staining:
Sudan IV is used as a biological stain for lipid-containing substances. Its affinity for lipids allows it to selectively stain these substances, making them more visible under microscopic examination. This property is particularly useful in histology and pathology for the identification and analysis of lipid-rich tissues and cells.
Used in Industrial Applications:
As a member of the Sudan dye family, Sudan IV is also used in various industrial applications, such as the coloring of waxes, oils, and varnishes. Its ability to impart a deep red color makes it a popular choice for these purposes.
However, it is important to note that the use of Sudan IV in food coloring has been subject to regulation in various countries due to concerns about its potential health risks, including being a potential carcinogen. As a result, its use in the food industry has been limited or banned in some regions to ensure consumer safety.
Check Digit Verification of cas no
The CAS Registry Mumber 68310-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,1 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.Calculate Digit Verification of CAS Registry Number 68310-04:
(7*6)+(6*8)+(5*3)+(4*1)+(3*0)+(2*0)+(1*4)=113
113 % 10 = 3
So 68310-04-3 is a valid CAS Registry Number.
