Solubilizes proteins by reducing disulfide linkages2-Mercaptoethanol is used in the preparation of nano-graphene for cellular imaging and drug delivery as well as multifunctional polymeric micelle. It acts as a reducing agent used in electrophoresis, amino acid detection, and distinguishing ssDNA/dsDNA. It is also employed as a standard buffer. It is also used in the preparation of PVC heat stabilizers and as a chain transfer agent in the manufacture of PVC. Further, it is used in some RNA isolation procedures to eliminate ribonuclease. It is utilized as a corrosion inhibitor and ore floatation agent. In biochemistry, it is useful to study the activity of the immune system.


Hygroscopic. Air sensitive and heat sensitive. Incompatible with metals, strong acids, heavy metal salts and oxidizing agents. Store in a cool place.

Amberlyst 15 is also effective: Synthesis, 1826 (2001), as is In(OTf)3: Synlett, 1535 (2002). 1,3-Oxathiolanes can be prepared from acid-sensitive aldehydes with LiBH4 as catalyst in acetonitrile: Synlett, 238 (2001). Cleavage can be effected, e.g. with chloramine-T: Tetrahedron Lett., 3445 (1971), isoamyl nitrite: Tetrahedron. Lett., 3561 (1978), or periodic acid: Tetrahedron Lett., 37, 4331 (1996). Selective cleavage of oxathiolanes in the presence of dithiolanes has been achieved with triphenylcarbenium tetrafluoroborate: J. Chem. Soc., Perkin 1, 542 (1972), or 4-nitrobenzaldehyde catalyzed by TMS-OTf: J. Chem. Soc. Chem. Commun., 1937 (1994). Compare 1,2-Ethanedithiol, L12865.
