Tris-HCL - Uses and synthesis methods
Introduction
Trimethylolaminomethane hydrochloride is abbreviated as Tris-HCl. Trihydroxymethyl aminomethane hydrochloride buffer (Tris-HCl buffer) is not only widely used as a solvent for nucleic acids and proteins, but also has many important uses.
application
Tris-HCl are used for protein crystal growth under different pH conditions. The low ionic strength characteristics of Tris-HCL buffer can be used for the formation of intermediate fibers of nematode (C. elegans) nuclear lamin. Tris-HCl is also one of the main components of protein electrophoresis buffer. In addition, Tris-HCL is also an intermediate for preparing surfactants, vulcanization accelerators and some drugs. Tris-HCl are also used as titration standards.
Buffer solution preparation
trimethylolaminomethane hydrochloride was used as solute, deionized water was used as solvent, and HCl aqueous solution with concentration of 0.1mol/L was used to adjust pH value to prepare trimethylolaminomethane hydrochloride buffer solution (Tris-HCl buffer solution) with concentration of 6.057g/L and pH = 8.8.
chemical properties
White crystals.
Use
The pH of all buffers depends on temperature and concentration. For Tris buffer, the temperature increases by about 0.03 units for every 1°C pH increase, and the dilution pH decreases by 0.03-0.05 units for every 10 times.
For biological buffer
Used as an intermediate in organic synthesis
