Uv-Vis Spectrum of n-Benzylmethylamine

February 25, 2026

Access the UV-Vis Spectrum SIELC Library

If you are looking for optimized HPLC method to analyze N-Methylbenzylamine 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.

Application Analytes:

Primesep C Column Retention Control

March 27, 2004

Primesep C separates benzylamines with an easily tunable HPLC method that allows retention control. Benzylamine, N-methylbenzylamine, and N,N-dimethylbenzylamine peak order and retention can be significantly changed by altering the water/acetonitrile ratio in the mobile phase which changes the combination of cation exchange, complex formation, and hydrophobic interactions. This mixture is separated with a mobile phase of water, acetonitrile (MeCN, ACN) and triethylamine (TEA) phosphate with UV detection at 210 nm.

Condition
Column Primesep C, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O
Buffer TEAPh
Flow Rate 1.0 ml/min
Detection UV 210

Description
Class of Compounds Hydrophilic, Ionizable
Analyzing Compounds Benzylamine, N-methylbenzylamine,  N,N-dimethylbenzylamine
