While N,N-Bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (BES) is widely recognized for its crucial role as a biological buffer in biochemistry and molecular biology, its utility extends to several other fascinating scientific domains. As a zwitterionic compound with a specific chemical structure, BES possesses properties that make it valuable in applications beyond simple pH stabilization. Exploring these diverse roles provides a deeper understanding of its versatility and importance in scientific research and development.

One such less-discussed application of BES is its function as a cross-linking agent. Its structure, featuring hydroxyl groups, allows it to participate in reactions that induce cross-linking between polymer chains. Specifically, BES has been utilized to cross-link sulfonated polyimide chains in sulfonated polyimide membranes. This property is significant in materials science, particularly in the development of advanced membranes for filtration, separation, or other specialized applications where precise control over membrane structure and properties is required. The ability to buy BES for these specialized material science applications highlights its broad chemical reactivity.

Furthermore, BES has found utility in the study of self-assembly processes. Researchers have employed it as a biobuffer to investigate the aqueous medium self-assembly of complex structures, such as heterometallic CuII/Li 3D coordination polymers. In these studies, BES not only helps maintain the appropriate pH for the self-assembly reactions but may also influence the nucleation and growth of the resulting crystalline structures through coordination or templating effects. This showcases BES's potential in supramolecular chemistry and the design of novel functional materials.

The compound's interaction with DNA also extends beyond its role in transfection. BES has been investigated for its effect on the binding of copper ions to DNA and its influence on DNA-protein interactions in various buffer systems. Understanding these molecular interactions is crucial for developing new analytical techniques and for comprehending cellular processes at a deeper level. The availability of BES from suppliers like NINGBO INNO PHARMCHEM CO.,LTD. ensures that scientists can explore these complex biochemical interactions effectively.

Additionally, BES has been noted for its role in minimizing interfering factors in sensitive biological tests, such as the bacterial endotoxin test. Its presence in a solution can help ensure the accuracy of such tests, which are critical for quality control in pharmaceutical and medical device manufacturing. The consistent quality and purity of BES are paramount for these demanding applications, making the selection of a reliable supplier crucial. When researching the price of BES, it's important to consider these varied applications and the specific grade required.

In conclusion, N,N-Bis(2-hydroxyethyl)-2-aminoethanesulfonic acid (BES) is a remarkably versatile chemical. While its primary function as a biological buffer is well-established, its capabilities as a cross-linking agent, in self-assembly studies, and in enhancing the accuracy of specific biological tests demonstrate its broad scientific impact. The continuous supply of high-quality BES by providers like NINGBO INNO PHARMCHEM CO.,LTD. enables scientists across diverse fields to innovate and achieve groundbreaking results.
