Sodium Dodecyl Sulphate (SDS), also known as Sodium Lauryl Sulphate, is a popular anionic detergent used in various scientific and industrial applications.
 
Its CAS number is 151-21-3, and its molecular weight is 288.38 g/mol.
 
SDS is highly toxic if ingested or inhaled and can cause skin and eye irritation. Despite its hazards, SDS is commonly used in laboratories as a protein denaturant, emulsifier, and surfactant.
 
Its ability to solubilize and separate proteins makes it a valuable tool in biochemical research.
