Used primarily as an anionic surfactant in various industrial and laboratory applications. It is commonly employed in chromatography as a mobile phase additive to improve the separation of polar compounds, particularly in reversed-phase HPLC. Its ability to interact with analytes enhances detection sensitivity and resolution. In biochemical research, it serves as a solubilizing agent for proteins and other biomolecules, aiding in their study and analysis. Additionally, it finds use in the formulation of cleaning products, where its surfactant properties help in emulsifying oils and removing dirt. It is also utilized in the synthesis of certain organic compounds, acting as a phase-transfer catalyst to facilitate reactions.
