3-hydroxy-4-p-tolylazo-naphthalene-2,7-disulfonic acid is a complex organic compound with the molecular formula C18H16N2O7S2. It is characterized by the presence of a hydroxyl group, an azo group, and two sulfonic acid groups. 3-hydroxy-4-p-tolylazo-naphthalene-2,7-disulfonic acid is derived from naphthalene, a polycyclic aromatic hydrocarbon, and features a p-tolylazo group, which is a substituted azo group with a p-tolyl (a methyl group attached to a phenyl ring). The disulfonic acid groups provide the molecule with acidic properties and water-solubility. This chemical is often used as a chromogenic agent in analytical chemistry for the detection and quantification of certain metal ions, particularly in colorimetric assays. Its structure and properties make it a valuable tool in the field of chemical analysis, where it can form colored complexes with specific ions, facilitating their detection and measurement.

5859-08-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5859-08-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,5 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.Calculate Digit Verification of CAS Registry Number 5859-08:
(6*5)+(5*8)+(4*5)+(3*9)+(2*0)+(1*8)=125
125 % 10 = 5
So 5859-08-5 is a valid CAS Registry Number.
