General Description
4-[(4-Amino-5-methoxy-2-methylphenyl)azo]benzenesulfonic acid is a chemical compound with the molecular formula C13H14N2O4S. It is commonly used as a dye intermediate and in the production of azo dyes, which are widely used in the textile and paper industries. 4-[(4-Amino-5-methoxy-2-methylphenyl)azo]benzenesulfonic acid is an azo dye, meaning it contains a nitrogen-nitrogen double bond. It is a red to orange powder with limited solubility in water and is mainly used as a colorant for various materials. Additionally, it has been studied for its potential use in biomedical applications, such as in fluorescence-based cell imaging and as a potential treatment for certain types of cancers.
Check Digit Verification of cas no
The CAS Registry Mumber 40947-69-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,4 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40947-69:
(7*4)+(6*0)+(5*9)+(4*4)+(3*7)+(2*6)+(1*9)=131
131 % 10 = 1
So 40947-69-1 is a valid CAS Registry Number.

An anisotropic dye film having high dichromatic properties is provided. An anisotropic dye film wherein the period d attributable to molecular stacking is at most 3.445 ?, and the column length L thereof is at least 105 ?. The anisotropic dye film preferably has a degree of orientation of the molecular stacking axes of at least 85% and a film thickness of at most 30 μm, and is formed by a wet film-forming method. Since it has a molecular alignment suitable to develop a dichroic ratio, it provides high dichromatic properties. A polarizing element having this anisotropic dye film is excellent in heat resistance, light fastness and polarizing performance.
