Uv-Vis Spectrum of Vanillin
February 23, 2026
Access the UV-Vis Spectrum SIELC Library

If you are looking for optimized HPLC method to analyze Vanillin check our HPLC Applications library
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 Vanillin on Primesep SB Column on Alltesta™

HPLC Method for Vanillin on Primesep SB by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Vanillin
Vanillin is an organic compound with the molecular formula C8H8O3. It is what gives vanilla beans their scent and flavor. It is often used in food preparation as flavoring or in fragrances for it’s scent. Due to the scarcity of the natural compound, artificial versions have been developed.
Vanillin can be retained and analyzed using the Primesep SB stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a ammonium formate buffer. Detection is performed using UV.
