Widely used in laboratories for calibration and quality control in analytical techniques, especially in chromatography and electrophoresis. Ensures consistent and accurate measurement of surfactant concentrations in various samples. Commonly applied in environmental testing to determine surfactant levels in water and wastewater. Also utilized in pharmaceutical and cosmetic industries to validate cleaning procedures and detect residual surfactants. Its standardized concentration makes it ideal for creating reliable calibration curves and maintaining compliance with regulatory standards.
