HPLC Determination of Carbocisteine on Primesep 100 Column

July 31, 2019

Carbocisteine

Carbocisteine, or carbocysteine, is a drug designed to clear the mucus from the upper and lower airways. It’s primarily available in tablet form. It can be retained on a Primesep 100 Column in about 5 minutes. Primesep 100 is a reverse-phase (RP) mixed-mode column with embedded acidic ion-pairing groups.

Condition
Column Primesep 100, 4.6×150 mm, 5 µm, 100A
Mobile Phase MeCN/H2O – 10/90%
Buffer H2SO4 – 0.05 %
Flow Rate 1.0 ml/min
Detection UV, 200 nm

Separation of S-(Carboxymethyl)-L-cysteine on Newcrom R1 HPLC column

May 16, 2018
Separation of S-(Carboxymethyl)-L-cysteine on Newcrom R1 HPLC column

S-(Carboxymethyl)-L-cysteine 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.
