2-Mercaptoethanol, also known as 2-Hydroxy-1-Ethanethiol or 2-Hydroxyethylmercaptan, is a significant chemical compound with the CAS number 60-24-2 and chemical formula Cu00b2Hu00b6OS. This transparent, colorless liquid possesses a characteristic odor and is known for its solubility in water as well as various organic solvents like alcohols and ether.

Chemically, 2-Mercaptoethanol is both an alcohol and a thiol. Its dual functionality contributes to its versatility in numerous chemical reactions and applications. It is a toxic and flammable substance, necessitating careful handling and storage in accordance with safety protocols. Key physical properties include a boiling point of approximately 157u00baC and a flashing point of around 73.9u00baC. Its density is roughly 1.11 g/cmu00b3. The purity of 2-Mercaptoethanol is a critical factor for its efficacy in specialized applications, with high-quality grades often exceeding 99.5% purity, meeting stringent standards for moisture content, color, and pH.

The applications of 2-Mercaptoethanol span a wide array of industries and scientific disciplines. In the field of biochemistry and molecular biology, it is indispensable as a reducing agent. Its ability to cleave disulfide bonds is crucial for the denaturation of proteins, enabling their separation and analysis through techniques like SDS-PAGE. It is also commonly used in RNA isolation procedures to inhibit ribonucleases (RNases) by reducing their disulfide bonds, thereby protecting RNA integrity. This makes it a staple in research laboratories worldwide, underpinning fundamental biological studies.

Beyond biological research, 2-Mercaptoethanol finds extensive use in the polymer industry. It serves as a chain transfer agent in radical polymerization, helping to control the molecular weight distribution of polymers like poly(acrylate)s. It can also function as a catalyst, crosslinking agent, or resin curing agent in the synthesis of various polymeric materials, including polypropylene and polyvinyl chloride (PVC). Its chemical structure allows it to participate in reactions that modify the properties and structure of polymers, enhancing their performance for specific applications.

Furthermore, 2-Mercaptoethanol is a valuable intermediate in organic synthesis. It is used in the production of various fine chemicals, including dyes, pesticides, and pharmaceuticals. Its thiol group can be readily functionalized, making it a building block for more complex molecules. In the textile industry, it is employed in dyeing and finishing processes. It also serves as an additive in rubber manufacturing and paint formulations. Due to its chemical properties, it can act as a metal corrosion inhibitor and passivation agent in certain systems.

The quality specifications for 2-Mercaptoethanol are typically defined by parameters such as purity (often required to be 99.5% or higher), water content, color (measured by the Hazen or Pt-Co index), density, and pH of its aqueous solution. These specifications ensure the product's suitability for demanding industrial and research applications where consistent performance is essential. Packaging typically includes 200L plastic drums or IBC tanks, designed for safe transport and storage of this liquid chemical.
