Tris hemisulfate (CAS 6992-38-7)

Tris hemisulfate, a derivative of the widely utilized laboratory buffer Tris (tris(hydroxymethyl)aminomethane), exhibits unique buffering capabilities, particularly in biological and chemical research. Its structure includes a Tris base linked to a hemisulfate group, which modifies its solubility and enhances its buffering action within the acidic to neutral pH range. This chemical′s mechanism of action revolves around its ability to stabilize pH by absorbing excess hydrogen ions or donating them when necessary, thus maintaining a consistent environment crucial for various biochemical reactions. In research, Tris hemisulfate is primarily used for protein and nucleic acid isolation, where maintaining a stable pH is essential for preventing the degradation of these sensitive molecules. Additionally, it plays a vital role in electrophoresis, especially in the preparation of running buffers where precise pH control is crucial for the proper migration and separation of biomolecules. Its efficacy in buffering at lower pH levels makes it particularly useful in applications requiring a more acidic environment, such as certain enzymatic reactions where enzyme activity is optimized at a lower pH. Tris hemisulfate′s capacity to provide a stable ionic strength and pH without introducing contaminants or interfering with biological processes makes it a preferred choice for researchers engaged in detailed molecular biology studies and biochemical assays.
