HPLC Method for Carbocisteine, Methylparaben sodium, Propylparaben sodium, Propylparaben, Methylparaben on Primesep 100 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Carbocisteine, Methylparaben sodium, Propylparaben sodium, Propylparaben, Methylparaben.
Carbocysteine is a medication that reduces the viscosity of mucus making it easier to cough up. Methylparaben and propylparaben are used as preservatives in cosmetics, pharmaceuticals and food. They can be separated in HPLC on a Primesep 100 mixed-mode column by both hydrophobic and ionic properties present on the stationary phase. The analytical method uses acetonitrile (ACN) gradient and water with sulfuric acid (H2SO4) as buffer and UV detected at 200nm.

HPLC Method for Carbocisteine, S-(Carboxymethyl)-L-cysteine on Primesep 100 by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Carbocisteine, S-(Carboxymethyl)-L-cysteine.
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.
