Tris Base, scientifically known as Tris(hydroxymethyl)aminomethane (CAS 77-86-1), is a chemical compound with a remarkable range of applications, stemming from its fundamental chemical properties. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality Tris Base, essential for understanding its critical role in various scientific disciplines.

At its core, Tris Base is an organic amine with a molecular formula of C4H11NO3. Its defining characteristic is its ability to act as a buffer. The pKa of Tris Base is approximately 8.1 at 25°C, which means it is most effective at maintaining a stable pH in solutions ranging from 7.0 to 9.2. This pH range is particularly significant as it encompasses the physiological pH of many biological systems. The buffering action occurs through the equilibrium between the protonated form (Tris-H+) and the unprotonated form (Tris) of the molecule. When an acid is added, the unprotonated Tris accepts protons, and when a base is added, the protonated Tris donates protons, thereby resisting significant changes in pH.

This precise buffering capability makes Tris Base indispensable in numerous applications. In biochemistry and molecular biology, it is used to prepare buffers critical for enzyme assays, DNA/RNA manipulation, and electrophoresis. Its use in TAE and TBE buffers, for instance, ensures the stability of DNA during separation. Furthermore, Tris Base is valued in protein crystallization due to its ability to provide a stable environment for protein folding and crystal formation.

Beyond the laboratory, Tris Base finds utility in the pharmaceutical industry as an intermediate and excipient, contributing to drug stability and formulation. In cosmetics, it acts as a pH adjuster and emulsifier, enhancing the performance and feel of personal care products. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying Tris Base that meets the rigorous purity standards demanded by these diverse applications, ensuring reliable performance.

Understanding the chemistry of Tris Base is key to appreciating its broad impact. Its ability to maintain pH stability and its versatile functional groups make it a foundational chemical in scientific research and industrial applications, a testament to its broad use as a chemical for scientific research and industrial processes.
