General Description
A water-white liquid. May be toxic by ingestion, inhalation, or skin absorption.
Reactivity Profile
Organosulfides, such as THIOGLYCOL(60-24-2), are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. Reactions with these materials generate heat and in many cases hydrogen gas. Many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid.
Air & Water Reactions
No rapid reaction with air. No rapid reaction with water.
Hazard
Toxic by inhalation and ingestion.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Chemical Properties
Clear colorless liquid. 2-mercaptoethanol (bME) is a popular effective reducer, but extremely pungent.
Uses
2-Mercaptoethanol is used in the synthesis of nano-graphene for cellular imaging and drug delivery. Also used in the synthesis of multifunctional polymeric micelle used in specific targeting of tumor disruption.
Uses
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.
Application
2-Mercaptoethanol is used in the synthesis of nano-graphene for cellular imaging and drug delivery. Also used in the synthesis of multifunctional polymeric micelle used in specific targeting of tumor disruption.
Definition
ChEBI: 2-Mercaptoethanol is a primary alcohol and an alkanethiol. It has a role as a geroprotector.
Purification Methods
Purify it by distilling in a vacuum. Distilling at atmospheric pressure causes some oxidation and should be done in an inert atmosphere. [Woodward J Chem Soc 1892 1948.] It has a foul odour, is irritating t o the eyes, nose and skin — should be handled in an efficient fume cupboard. It is miscible with H2O, EtOH, Et2O and *C6H6 and the UV has max at 235nm. The 2,4-dinitrophenyl thioether has m 101-102o (from EtOH or aqueous MeOH) [Grogen et al. J Org Chem 20 50 1955].
