Tris and Tris hcl are well-known biological buffering agents, with the chemical names Trihydroxymethylaminomethane and Trihydroxymethylaminomethane hydrochloride. Tris base, a chemical substance that seems unfamiliar, is related to the two chemicals mentioned above?

Tris base powder

Tris base is actually a relatively complete English alias for tris, which means "base" in Chinese, indicating that tris is an alkaline substance, which is consistent with the acidity and alkalinity of tris aqueous solutions. This means that tris and tris base are two different names for the same substance.

Tris base and Tris hcl are two different biological buffering agents, which are introduced one by one below:

1. Different pH values

The pH value of Tris base aqueous solution at 25 ℃ is between 10.5 and 12.0, indicating an alkaline solution; Tris hcl is an acidic solution with a pH value between 2.5 and 4.0 in aqueous solution at 25 ℃. Due to their different pH values and corresponding buffer ranges, the applicable biochemical experiments are also different, and tris hcl is prepared by configuring tris base and hydrochloric acid.

2. Different scope of application

Tris base can be used for protein crystal growth under different acid-base conditions, as well as for pharmaceutical intermediates and the preparation of active agents; Tris HCl is widely used in nucleic acid and protein solvents, and can also form electrophoretic solutions with glycine. It can also be developed as an adjunct for use in some pharmaceutical products.

3. Differences in other aspects

Tris base and Tris hcl have different acidity coefficients, molecular formula, molecular weight, CAS number, etc. at room temperature, except for different pH values and buffer ranges. Although their appearance is white crystalline powder, their detailed information is still easily recognizable upon careful observation.
