2-Mercaptoethanol (CAS 60-24-2) is a high-purity thiol and reducing agent in the form of a clear, colorless liquid with a 99% minimum assay, used to break disulfide bonds in biochemical research and as a chain transfer agent in polymer and agrochemical production. It is essential in biochemical research and chemical synthesis for breaking disulfide bonds and preventing protein oxidation.

This clear liquid features a 99% minimum assay and a characteristic strong odor. It is a critical intermediate in the production of agrochemicals and plastics, where it serves as a chain transfer agent.

As a commercially vital thiol, it provides superior reactive properties for the modification of polymers and resins. Its ability to control molecular weight during polymerization makes it indispensable in specialty plastic manufacturing.
