Sodium dodecyl sulfate (SDS), a highly effective anionic surfactant, is widely used as a detergent, emulsifier, and solubilizing agent in laboratories, pharmaceuticals, and industrial cleaning applications. It disrupts cell membranes and protein structures, making it essential for cell lysis, DNA/protein extraction, and analytical processes like electrophoresis. This 20% SDS solution has a CAS number of 151-21-3, with the molecular formula C12H25NaO4S and a molecular weight of 288.38 g/mol. Store at ambient temperature, handling with caution—it carries a **Danger** signal word due to its corrosive and hazardous nature. Molekula supplies SDS Solution 20% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
