2-thio-glycolicaci - Introduction
Mercaptoacetic acid, also known as Mercaptoacetic acid, is an organic compound. The following is an introduction to the nature, use, formulation and safety information of Mercaptoacetic acid:
Nature:
- Mercaptoacetic acid is a colorless or yellowish liquid with a strong pungent odor.
-It is soluble in water and many organic solvents, and is relatively stable in the air.
-It is a weak acid that can react with alkali to generate the corresponding salt.
Use:
- Mercaptoacetic acid is widely used in chemical analysis and laboratory research.
-It is often used as a complexing agent for metal ions and can form a complex combined with metal ions.
-In biochemistry, Mercaptoacetic acid is an important reducing agent that can be used to reduce the disulfide bonds of proteins.
Preparation Method:
Mercaptoacetic acid can be synthesized by the following steps:
1. the reaction of sodium chloroacetate and propylene chloride in ethanol solution to generate propylene chloroacetate.
2. react propylene chloroacetate with ammonia water to generate ammonia condensation hydrate of Mercaptoacetic acid.
3. ammonia hydrate is condensed by acidification reaction to obtain pure Mercaptoacetic acid.
Safety Information:
- Mercaptoacetic acid is irritating to eyes, skin and respiratory tract, wear appropriate protective equipment when using it.
-Avoid exposure of Mercaptoacetic acid to ignition or oxidizer to prevent fire or explosion.
- Mercaptoacetic acid is a corrosive substance and should be stored in a sealed container, away from organic matter and combustibles.
-When using Mercaptoacetic acid, pay attention to the correct operation and disposal methods to ensure safety.
