2-Mercaptoethanol
CAS #:
60-24-2
Used as a reducing agent in organic reactions and for retarding oxidation of biological compounds in solutions.

2-Mercaptoethanol, also known as BME, is a potent chemical reducing agent used in breaking disulfide bonds in proteins. 2-Mercaptoethanol stands out as one of the best oilfield additives for oxidation and corrosion control. With strong reducing power, excellent thermal stability, and high compatibility, it provides a reliable, sulfur-free alternative to traditional sulfite-based reducers.
2-Merc is used industrially as a chain transfer agent in polymer and rubber production, a corrosion inhibitor, and a stabilizer in PVC manufacturing. It also functions as an intermediate in the synthesis of other chemicals, including those used in agrochemicals, dyes, and pharmaceuticals, and has applications in metal finishing, water treatment, and as a component in cleaning agents and hair dyes.
