Applications

• Biological Buffer: TES is an important biological buffer, suitable for various cell culture systems that require divalent metal ions. Many other buffers, such as citrates or phosphates, can cause chelation or precipitation reactions, making them unable to meet this requirement. In addition, TES is extremely beneficial for the study of succinate oxidation reactions. TES has been used in TES buffers and can also be used as a buffer in cell culture media.
• Medical Detection: It can be used as a buffer in creatinine detection reagents and other medical detection fields.
• Other Fields: It is also used in conductive materials. Adding TES to conductive polymers with sulfonic acid groups and/or carboxyl groups can greatly improve the conductivity and heat resistance of the resulting composition.

Storage Conditions

• It can be transported and stored at room temperature, and it is stable for at least three years. The solution should be stored at 2 - 8°C and is stable for at least six months.
