Explanation
Methyl Red is a red-colored dye used in various industries.
Explanation
Methyl Red is commonly used in these industries as a colorant.
Explanation
Methyl Red changes color from red to yellow when the pH level is between 4.4 and 6.2.
Explanation
The dye changes color in response to the pH level, which is useful as a pH indicator.
Explanation
Methyl Red belongs to the azo dyes family, which are known for their color-changing properties.
Explanation
This is the process through which Methyl Red is typically synthesized.
Explanation
The presence of sulfonic acid groups makes Methyl Red soluble in water.
Explanation
Methyl Red can interact with proteins and other biological molecules due to its acidic nature and water solubility.

Check Digit Verification of cas no
The CAS Registry Mumber 40136-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,3 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40136-84:
(7*4)+(6*0)+(5*1)+(4*3)+(3*6)+(2*8)+(1*4)=83
83 % 10 = 3
So 40136-84-3 is a valid CAS Registry Number.
