HPLC Separation of β-Lactam Antibiotics such as Amoxicillin and Cephalexin on Primesep 100 Column

March 18, 2021

HPLC Method for Cephalexin, Amoxicillin, Amoxicillin hydrate (1:3) on Primesep 100 by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Cephalexin, Amoxicillin, Amoxicillin hydrate (1:3).

Both amoxicillin and cephalexin are beta-lactam antibiotics. Beta-lactam antibiotics contain a beta-lactam ring in their molecular structure. As a group, these drugs are active against many gram-positive, gram-negative and anaerobic organisms. Amoxicillin is a prescription antibiotic with the molecular formula C16H19N3O5S. It is typically used to treat bacterial infections and is taken orally.  Cephalexin has the chemical formula C16H17N3O4S.

Cephalexin, Amoxicillin, Amoxicillin hydrate (1:3) can be retained and baseline separated with an isocratic method in 30/70 Acetonitrile (ACN) and water mobile phase with a Sulfuric acid (H2SO4) buffer. UV detection at 250 nm.

Separation of Amoxicillin hydrate (1:3) on Newcrom R1 HPLC column

February 16, 2018
Separation of Amoxicillin hydrate (1:3) on Newcrom C18 HPLC column

Amoxicillin hydrate (1:3) 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.
