21542-82-5 Usage
Uses
Used in Textile Industry:
Acid Yellow 10 is used as a coloring agent in the textile industry for its good light and wash fastness, making it suitable for coloring fabrics and garments.
Used in Food Industry:
Acid Yellow 10 is used as a coloring agent in the food industry, commonly seen in products such as mustard, sauces, and desserts. Its bright yellow color enhances the visual appeal of these food items.
However, there are concerns about the potential environmental impact of Acid Yellow 10 and the possibility of allergic reactions in some individuals due to its synthetic nature.
Check Digit Verification of cas no
The CAS Registry Mumber 21542-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,4 and 2 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21542-82:
(7*2)+(6*1)+(5*5)+(4*4)+(3*2)+(2*8)+(1*2)=85
85 % 10 = 5
So 21542-82-5 is a valid CAS Registry Number.

Low concentrations of nitrogen dioxide, which arises as a side product from a range of industrial processes, can effectively be recycled through the diazotization of anilines. The studies reported herein now demonstrate that the removal of nitrogen dioxide from gas streams is even more effective when hydrophilic anilines are used as starting materials. The diazonium salts, which are obtained in this way in up to quantitative yields, can directly be employed in azo coupling reactions, thus opening up an attractive route to the industrially important group of azo compounds.
