23299-85-6 Usage
General Description
COPPER PAN (CU-EDTA + PAN) is a chemical solution comprised of copper (Cu) and ethylenediaminetetraacetic acid (EDTA) and 1-(2-pyridylazo)-2-naphthol (PAN). This solution is commonly used in analytical chemistry for the determination of copper ions in samples. The EDTA chelates with the copper ions to form a stable complex, while PAN reacts with the complex to produce a colored compound. The intensity of the color can then be measured spectrophotometrically to determine the concentration of copper in the sample. This chemical is widely utilized in laboratories for its accuracy and sensitivity in copper analysis.
Check Digit Verification of cas no
The CAS Registry Mumber 23299-85-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,2,9 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 23299-85:
(7*2)+(6*3)+(5*2)+(4*9)+(3*9)+(2*8)+(1*5)=126
126 % 10 = 6
So 23299-85-6 is a valid CAS Registry Number.

Far-infrared studies of Cu(II)-1-(2-pyridylazo)-2-naphtol complexes by metal isotope technique
Drozdzewski, Piotr M.
, p. 855 - 858 (1982)
The metal isotope technique is applied to the investigation of the metal-ligand bands in the i.r. spectra of complexes of type: Cu(PAN)X and Cu(PAN)2 where X = Cl, Br and PAN symbolizes 1-(2-pyridylazo)-2-naphtol.For the Cu(PAN)Cl complex, bands 337, 274 and 196 cm-1 were assigned to the Cu-O, Cu-N-py and Cu-N-azo stretching vibrations, respectively.Two Cu-Cl stretching vibrations have been found at 298 and 236 cm-1.The spectrum indicates that in the Cu(PAN)2 complex.PAN acts as a bidentate ligand as only Cu-O and Cu-N-azo bonds are formed.
