1-Hexanesulfonic acid sodium salt monohydrate is a crystalline anionic alkylsulfonate salt used as an ion-pair reagent in the mobile phase for high-performance liquid chromatography (HPLC), where it increases the retention of ionic analytes, mainly basic or cationic compounds such as amines, in reversed-phase separations. It is a white to off-white crystalline solid with high solubility in water and polar organic solvents, making it ideal for reversed-phase separations. This product has a CAS number of 207300-91-2, a molecular formula of CH3(CH2)4CH2SO3Na · H2O, and a molecular weight of 206.24. It should be stored at ambient conditions and handled with caution, as it carries a warning signal word for potential hazards. Molekula supplies 1-Hexanesulfonic acid sodium salt monohydrate for HPLC from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
