SDS (Sodium dodecyl sulfate)
ISO 9001:2015 & ISO 14001:2015 certified · Supplying laboratories and industry since 2000 · Certificate of Analysis with every batch
Sodium dodecyl sulfate (SDS) is an anionic surfactant widely used as a detergent, emulsifier, and wetting agent in laboratories, pharmaceuticals, and industrial cleaning applications. It is a key component in cell lysis buffers, household detergents, and personal care products due to its strong solubilizing properties. This chemical has a CAS number of 151-21-3, with the molecular formula C12H25NaO4S and a molecular weight of 288.38 g/mol. It is stored at ambient conditions but requires careful handling, as it carries a **Danger** signal word for its hazardous nature. Molekula supplies SDS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
