Sodium 1-decanesulfonate is a high-purity anionic surfactant primarily used as an ion-pairing agent in ion-pair chromatography (IPC) for the separation and analysis of charged molecules, such as nucleotides, peptides, and pharmaceuticals. Its ≥99.5% purity and low UV absorbance ensure minimal interference in HPLC and other chromatographic techniques. Additionally, it is widely employed as a surfactant in industrial and household cleaning products due to its excellent foaming and emulsifying properties, reducing surface tension for use in detergents, shampoos, and soaps. In the textile industry, it acts as a wetting agent and dye dispersant to enhance dye distribution on fabrics. It is also utilized in agrochemical formulations as a spreading agent to improve pesticide and herbicide coverage and absorption on plant surfaces. Its chemical stability and compatibility make it versatile across various applications.
