Description

· HPLC Method for Analysis of Methanesulfonic Acid on Primesep B Column by SIELC Technologies

Methanesulfonic acid (MSA) is an organosulfur compound with the chemical formula CH₄O₃S or structurally CH₃SO₃H. It is the simplest alkane sulfonic acid, consisting of a methyl group Applications: Catalysis: Used as a strong acid catalyst in organic and industrial chemical reactions, including esterifications and polymerizations. Electroplating: An electrolyte component in electroplating baths, especially for tin and tin-lead plating. Cleaning: Employed in industrial cleaning due to its strong acidity and non-oxidizing nature. Pharmaceuticals: Used in the preparation of certain drugs, intermediates, and active pharmaceutical ingredients. Alternative to Sulfuric Acid: Often preferred in specific applications because it is non-volatile and less corrosive to metals.

Methanesulfonic Acid can be retained, and analyzed using a Primesep B mixed-mode stationary phase column. The analysis utilizes a gradient method with a simple mobile phase consisting of water, acetonitrile (MeCN), and phosphoric acid as a buffer. Detection is carried out using UV.
