Sodium decyl sulfate is a surfactant used in the preparation of biological samples for analysis using mass spectrometry. This compound forms a disulfide bond with cysteine residues on proteins, which can be cleaved by reducing agents such as dithiothreitol or mercaptoethanol. Sodium decyl sulfate also has potent antitumor activity and is used to treat autoimmune diseases such as multiple sclerosis. The thermal expansion of this compound is proportional to the vapor pressure of water over the range from 0-100C, and it has been shown to have a constant pressure at temperatures below 100C. Furthermore, sodium decyl sulfate has been found to be chiral and binds to receptor molecules that are hydrophobic in nature.
