Trisodium 5-amino-3-[[4-[[4-[(7-amino-1-hydroxy-3-sulphonato-2-naphthyl)azo]phenyl]azo]phenyl]azo]-4-hydroxynaphthalene-2,7-disulphonate is a complex organic compound with the chemical formula C34H23N7Na3O8S3. It is a type of azo dye, characterized by its deep color and the presence of multiple azo groups (-N=N-) in its structure. trisodium 5-amino-3-[[4-[[4-[(7-amino-1-hydroxy-3-sulphonato-2-naphthyl)azo]phenyl]azo]phenyl]azo]-4-hydroxynaphthalene-2,7-disulphonate is derived from naphthalene, a polycyclic aromatic hydrocarbon, and contains several hydroxyl, amino, and sulfonate functional groups. The trisodium salt form indicates that it has three sodium ions associated with it, which can influence its solubility and reactivity. This chemical is primarily used in the dyeing industry for coloring textiles and other materials, and its specific structure contributes to its colorfastness and stability under various conditions.

52469-75-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 52469-75-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,4,6 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 52469-75:
(7*5)+(6*2)+(5*4)+(4*6)+(3*9)+(2*7)+(1*5)=137
137 % 10 = 7
So 52469-75-7 is a valid CAS Registry Number.
