Uses
Used in Textile Industry:
1-(4-Trifluormethyl-phenylazo)-2-naphthol was traditionally used as a coloring agent for textiles, providing vibrant red-orange hues to fabrics. Its application was favored for its colorfastness and ability to produce a wide range of shades.
Used in Plastics Industry:
In the plastics industry, Sudan I was employed to impart color to various plastic materials, enhancing their visual appeal and providing a distinctive appearance to finished products.
Used in Wax Industry:
Sudan I was also utilized in the wax industry to color waxes, offering a consistent and attractive coloring solution for a range of wax applications.
However, due to its potential carcinogenic and mutagenic properties, the use of Sudan I has been banned in many countries. Prolonged exposure or ingestion of 1-(4-Trifluormethyl-phenylazo)-2-naphthol has been associated with an increased risk of liver and bladder cancer, as well as other adverse health effects. Consequently, it is crucial to regulate and monitor the use of Sudan I to safeguard human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 54397-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,3,9 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54397-98:
(7*5)+(6*4)+(5*3)+(4*9)+(3*7)+(2*9)+(1*8)=157
157 % 10 = 7
So 54397-98-7 is a valid CAS Registry Number.
