7-hydroxy-8-p-tolylazo-naphthalene-1,3-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. 7-hydroxy-8-p-tolylazo-naphthalene-1,3-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 confer water-solubility and acidic properties to the molecule. This chemical is often used as a chromogenic agent in analytical chemistry for the detection and quantification of certain metal ions, particularly due to its ability to form colored complexes upon interaction with these ions. Its applications may extend to various fields, including environmental monitoring, pharmaceutical analysis, and materials science, where its reactivity and color-changing properties are leveraged for sensitive and specific detection methods.

5859-09-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5859-09-6 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 9 respectively.Calculate Digit Verification of CAS Registry Number 5859-09:
(6*5)+(5*8)+(4*5)+(3*9)+(2*0)+(1*9)=126
126 % 10 = 6
So 5859-09-6 is a valid CAS Registry Number.
