Introduction to characteristics of trimethyl aminomethane

 

Trihydroxymethyl aminomethane, also known as Tris, CAS No. 77-86-1, is a white crystalline powder substance. Its main function is to adjust or maintain the PH value range of the solution between 7-9 without changing the original properties of the substance. It is a common biological buffer. What are the characteristics of this buffer? Through a simple understanding of it, we can know how to use it.

 

Characteristics of trimethylaminomethane:

1. Tris solution is weakly alkaline and is generally used in biochemistry, molecular biology, coating and other fields. Because TRIS buffer solution is easy to absorb carbon dioxide in the air, it must be sealed during storage to reduce contact with the air;

2. The PH range from acid to alkaline can be configured, which is generally the adjustment range of PH7-9.

3. The pH value of Tris will be affected by the concentration of the solution, so when configuring, it is necessary to control the dilution ratio of the solution. If the buffer is diluted 10 times, the pH value will change more than 0.1.

4. Pay attention to the indoor temperature during solution preparation, which should be carried out under the temperature conditions of specific use scenarios. For example, the solution prepared at room temperature of 30 ℃ can not be used in the temperature environment of 0 ℃~4 ℃.

5. Tris buffer solution has certain influence on the generation of PH electrode, so the electrode to be selected must be compatible with Tris solution.

6. Generally, everyone knows that Tris can be used in the field of biochemistry, but few people know that it can also be used in the field of paint. In the field of coatings, it generally prevents discoloration by adjusting the PH value of coatings. It can also be used to degrade formaldehyde in latex paint.
