Products Description of Sodium dodecyl sulfate CAS#151-21-3

Sodium dodecyl sulfate (SDS), with the chemical formula C12H25NaO4S, is a potent anionic surfactant that is soluble in water and widely used for its exceptional emulsifying, foaming, and wetting properties. It is a white crystalline powder that plays a critical role in the formulation of detergents, cleaners, and personal care products, and is particularly instrumental in protein electrophoresis as a denaturing agent. SDS is characterized by a molecular weight of approximately 288.4 g/mol, a high solubility in water, a critical micelle concentration around 8 mM, and a melting point above 200°C. It should be stored in tightly sealed containers, away from light and moisture, ideally at temperatures between 2-8°C, and handled with appropriate protective measures due to its potential for irritation.
