Ethanol, 2,2'-[[4-[(4-methoxyphenyl)azo]phenyl]imino]bis-, also known as C.I. 11102 or Solvent Yellow 3, is an organic compound with the chemical formula C20H20N4O2. It is a yellow-colored azo dye derived from ethanol, characterized by the presence of two phenyl rings connected through an azo group (-N=N-) and a 4-methoxyphenyl group. Ethanol, 2,2'-[[4-[(4-methoxyphenyl)azo]phenyl]imino]bis- is primarily used as a solvent dye in various industries, including printing, painting, and plastics, due to its excellent solubility and color properties. However, it is important to note that the use of such chemicals may have potential health and environmental concerns, and proper safety measures should be taken during handling and disposal.

3009-52-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3009-52-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3009-52:
(6*3)+(5*0)+(4*0)+(3*9)+(2*5)+(1*2)=57
57 % 10 = 7
So 3009-52-7 is a valid CAS Registry Number.

Synthesis and evaluation of changes induced by solvent and substituent in electronic absorption spectra of some azo disperse dyes

Mohammadi, Asadollah,Yazdanbakhsh, Mohammad Reza,Farahnak, Lahya

, p. 238 - 242 (2012)

Five azo disperse dyes were prepared by diazotizing 4′- aminoacetophenone and p-anisidine and coupling with varies N-alkylated aromatic amines. Characterization of the dyes was carried out by using UV-vis, FTIR and 1H NMR spectroscopic techniqu
