α-(2-carboxyphenylazo)-β-naphthylamine is a complex organic compound with the chemical formula C18H14N4O2. It is characterized by its azo group, which is a diazenyl (-N=N-) functional group, and its carboxylic acid group, which is a hydroxyl group (-OH) attached to a carbon atom of an alkyl or aryl group. α-(2-carboxyphenylazo)-β-naphthylamine is derived from naphthylamine, which is an aromatic amine, and features a 2-carboxyphenyl group attached to it through the azo linkage. It is often used as a chromogenic agent in analytical chemistry for the detection and quantification of certain metal ions, particularly copper, due to its ability to form colored complexes with these ions. The compound's structure and properties make it a valuable tool in colorimetric assays and other chemical analyses.

57039-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57039-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,3 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.Calculate Digit Verification of CAS Registry Number 57039-58:
(7*5)+(6*7)+(5*0)+(4*3)+(3*9)+(2*5)+(1*8)=134
134 % 10 = 4
So 57039-58-4 is a valid CAS Registry Number.
