Mercaptoethanol from the point of view of chemical formula see mercaptoethanol alpha - mercaptoethanol and beta mercaptoethanol, but alpha and - mercaptoethanol instability. The reason for this is hydroxyl and sulfhydryl even on the same carbon atom is unstable. In biology is often said of mercaptoethanol is mercapto ethanol.

2-mercaptoethanol (also known as beta mercaptoethanol) is a kind of organic compounds, the chemical formula for HOCH2CH2SH. English common abbreviations for me, or beta me. It has both functional groups of ethylene glycol (hoch2ch2oh) and ethyl Di thiol HSCH2CH2SH, is a volatile liquid, has a strong irritating smell. Beta me is usually used for disulfide bond reduction can as antioxidants in biological experiments. It is widely used in the is its hydroxyl so that it can be dissolved in water, and reduce its volatility. Because of its low steam pressure, its unpleasant than the stench of thiol is better.

Uses: alpha Mercaptoethanol is mainly used for serological agglutination test.Its clinical significance when the experimental value of >1 50 for the positive health search, the rate of the disease is 93.88%. Beta mercaptoethanol is mainly used for production of PVC with low degree of polymerization of chain transfer agent, acrylic terminator. Can also be used for synthetic polymeric materials cotelmer, polymerization catalyst, crosslinking agent and resin curing agent can also be used for synthetic rubber, photography, pharmaceuticals, paints, textile, metal passivating agent industry.

Thioglycol: dangerous goods! Through the skin, swallowing and absorbing the risk of fatal; to stimulate the eyes, respiratory mucosa, causing chronic pharyngitis!

The significance of b-Mercaptoethanol in biological experiments: Two sulfur bonds are opened to make the protein four or three of the structure is damaged. Since b-Mercaptoethanol are able to open the structure of a protein, it is often used in protein analysis. And b-Mercaptoethanol is also often used to protect the free cysteine thiol groups in the protein will not be wrong to form two sulfur bonds.

As a reducing agent, 2- mercaptoethanol can often and two dithiothreitol (DTT) or three (2- formyl ethyl) phosphine hydrochloride (TCEP) used interchangeably.

b-Mercaptoethanol is a small number of compounds that can prolong the life span of mice. At the level of the order of b-Mercaptoethanol was observed to have a variety of possible positive effects on the life of experimental rats.

Applications: used as plasticizer and pesticides, also for the dye manufacturing; used for synthesizing thio, dithiocarbamate, thio cyanate ester pesticides and herbicides; high purity products used in medicine, photosensitive material, rubber plastic additives, such as
