3-Ethyl-4-(2-nitro-phenylazo)-phenol is an organic compound characterized by its unique molecular structure, which consists of a phenol group with an ethyl substituent at the 3rd carbon and a 2-nitro-phenylazo group attached at the 4th carbon. This azo compound is known for its vibrant color and is often used as a dye in various applications. It is synthesized through a diazotization reaction, where a primary aromatic amine is reacted with nitrous acid to form a diazonium salt, which then couples with the phenol to form the azo bond. The compound's chemical properties include its solubility in organic solvents and its sensitivity to light, which can lead to color changes over time. It is important to handle 3-Ethyl-4-(2-nitro-phenylazo)-phenol with care due to its potential toxicity and the need for proper safety measures during its production and use.

3882-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3882-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,8 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 3882-71:
(6*3)+(5*8)+(4*8)+(3*2)+(2*7)+(1*1)=111
111 % 10 = 1
So 3882-71-1 is a valid CAS Registry Number.
