UV-Vis Spectrum of p-Phenylenediamine

October 3, 2024
UV-Vis Spectrum of Keracyanin. Absorption Maxima: 198 nm, 236 nm, 284 nm.

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

HPLC Method for Analysis of o-Phenylenediamine, , m-Phenylenediamine, p-Phenylenediamine on Primesep 100 Column


 High Performance Liquid Chromatography (HPLC) Method for Analysis of o-Phenylenediamine, , m-Phenylenediamine, p-Phenylenediamine

o-Phenylenediamine, m-Phenylenediamine, and p-Phenylenediamine are isomers of phenylenediamine, where the amino groups are attached to different positions on the benzene ring.

These compounds are important in various industrial applications due to their role as intermediates in the synthesis of other chemicals.

o-Phenylenediamine, , m-Phenylenediamine, p-Phenylenediamine can be retained, separated and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV 200 nm
