Used as an ion-pairing reagent in HPLC (High-Performance Liquid Chromatography) to improve the separation and retention of ionic compounds. Applied in pharmaceutical analysis for the quantification of drugs and related substances. Used in biochemical and environmental analysis to separate charged molecules. Functions as a surfactant in some laboratory and industrial formulations.

The primary purpose of 1-hexanesulfonic acid sodium salt is to enhance the chromatographic separation of positively charged or polar compounds by forming ion pairs thereby improving resolution retention and analytical accuracy in HPLC methods.

1-Hexanesulfonic acid sodium salt is an anionic surfactant and ion-pairing reagent. It is a white solid that is highly soluble in water and is commonly used in analytical chemistry.
