21542-82-5 Usage
General Description
Acid Yellow 10, also known as Quinoline Yellow, is a synthetic chemical dye used primarily in the textile and food industries. It is a disazo dye with a bright yellow color and is commonly seen in products such as mustard, sauces, and desserts. Acid Yellow 10 is used as a coloring agent and has good light and wash fastness, making it suitable for use in textiles. It is also known for its low toxicity and is considered safe for use in foods and textiles. However, like many synthetic dyes, there are concerns about its potential environmental impact and allergic reactions in some individuals.
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.

Sustainable Synthesis of Balsalazide and Sulfasalazine Based on Diazotization with Low Concentrations of Nitrogen Dioxide in Air
Hofmann, Dagmar,Gans, Eva,Krüll, Jasmin,Heinrich, Markus R.
, p. 4042 - 4045 (2017)
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.
