What Information Can Be Learned From The Quality Analysis Report (COA) Of The Biological Buffer CHES

1, Basic chemical information of CHES

In COA, the basic chemical information of CHES can be seen first. CHES, also known as 2- (N-cyclohexylamino) ethanesulfonic acid, has a chemical formula of C8H17O3NS, a relative molecular weight of 207.290, and a CAS number of 103-47-9. This unique numerical identification number not only marks the identity of CHES, but also serves as essential information for researchers in literature search, material purchase, and experimental records. In addition, to remind customers to use the product within its shelf life, the COA will also include the production date and shelf life of the product.

2, The physical properties of CHES

The physical properties of CHES are also an important part of COA. CHES usually exists in the form of white crystalline powder, which makes it easy to identify and handle in experimental operations. It is highly soluble in water, which makes CHES easy to operate when preparing buffer solutions and can quickly reach the desired concentration. In addition, the density, solubility and other parameters of CHES will also be provided in COA, providing detailed data support for researchers in experimental design and operation.

3, The buffering performance of CHES

As a biological buffering agent, the buffering performance of CHES is an important indicator for evaluating its quality. In COA, we can see that CHES exhibits high chemical stability over a wide range of pH values, especially in the pH range of 8.6-10.0, where its buffering capacity is particularly outstanding. This characteristic makes CHES an ideal choice for experiments under alkaline conditions, which can effectively maintain the pH stability of the solution and avoid deviations in experimental results.

4, Safety and precautions of CHES

Although CHES has many advantages, its safety should still be taken into account during use. COA will provide the safety level and hazard code of CHES, reminding researchers to wear protective goggles and gloves during operation to avoid direct skin contact or inhalation of its powder. In addition, the COA will mention the preservation method of CHES. CHES powder should be stored in a dry, sealed, cool, and dark environment to ensure its stability and effectiveness.

5, Quality control and performance testing of CHES

Some manufacturers may also include quality control and performance test results related to CHES in their COA quality analysis reports. These tests may involve pH stability at different temperatures, pH stability at different concentrations, determination of buffer capacity by acid-base titration, evaluation of buffer capacity by continuous dilution, performance changes at different ion strengths, compatibility with other ions, and thermal stability testing. Through these tests, we can comprehensively understand the performance characteristics of CHES and provide reliable basis for its application in the fields of chemistry and biology.
