Description

1-Pentanesulfonic acid sodium salt is a high-purity sulfonic acid salt widely used as a versatile ion-pairing reagent and mobile phase additive. Its primary value lies in enhancing chromatographic separation, particularly for polar and ionic compounds in reversed-phase HPLC and LC-MS applications. This product is essential for analytical chemists and formulators in the pharmaceutical, biotechnology, and chemical research industries seeking reliable and reproducible results.

Application

• As a key ion-pairing reagent in Reversed-Phase High-Performance Liquid Chromatography (RP-HPLC) for the analysis of basic compounds, peptides, and nucleotides.
• Mobile phase additive for improving peak shape and resolution in the LC-MS analysis of pharmaceuticals and biomolecules.
• Used in the purification and analysis of oligonucleotides and other polar biomolecules.
• Employed as a surfactant or phase-transfer catalyst in specialty organic synthesis.
• Component in analytical method development for compliance with pharmacopeial standards (e.g., USP, EP).
• Potential application in electrolyte formulations for electrochemical systems.
