HPLC Method for Analysis of 4-ethoxyaniline on Primesep 100 Column
May 6, 2022
Separation type: Liquid Chromatography Mixed-mode
High Performance Liquid Chromatography (HPLC) Method for Analysis of 4-ethoxyaniline
4-Ethoxyaniline, also known as p-Phenetidine, is one of three Phenetidine isomers, and is commonly used as an intermediate product in drug and dye synthesis. 4-Ethoxyaniline can be retained and analyzed on a mixed-mode Primesep 100 column with a mobile phase consisting of water, Acetonitrile (MeCN), and Sulfuric acid (H2SO4). This analytical method can be UV detected at 200 nm with high resolution and peak symmetry.
| Column | Promesep 100, 4.6×150 mm, 100A |
| Mobile Phase | MeCN – 40% |
| Buffer | H2SO4 – 0.2% |
| Flow Rate | 1.0 ml/min |
| Detection | UV 200nm |
| Class of Compounds | Aromatic amine |
| Analyzing Compounds | 4-ethoxyaniline |

Separation of 4-Ethoxyaniline on Newcrom R1 HPLC column
February 16, 2018
4-Ethoxyaniline can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
