Understanding the core chemistry of a compound is key to appreciating its wide-ranging applications. 4-Morpholineethanesulfonic Acid (MES), identified by its CAS number 4432-31-9, is a fascinating molecule whose structure dictates its valuable properties. NINGBO INNO PHARMCHEM CO.,LTD. supplies this essential chemical, enabling various industries and research fields to leverage its unique attributes.

At its heart, MES is a zwitterionic compound, meaning it carries both a positive and a negative charge within the same molecule. Its chemical formula is C6H13NO4S, and it has a molecular weight of approximately 195.24 g/mol. The molecule features a morpholine ring, a six-membered heterocycle containing both nitrogen and oxygen, attached to an ethanesulfonic acid group. This specific arrangement is what gives MES its characteristic behavior and makes it so effective in its various roles.

One of the most critical properties of MES, especially in its function as a biological buffer, is its pKa value. The pKa of MES is around 6.15 at 25°C. This value places it within the optimal buffering range for many biological systems, typically between pH 5.5 and 7.7. Biological processes, such as enzyme activity and cellular metabolism, are highly sensitive to pH changes. MES helps to maintain a stable pH environment, preventing drastic shifts that could denature proteins or disrupt cellular functions. Reliable suppliers of 4-morpholineethanesulfonic acid ensure the purity required for these sensitive applications.

The solubility of MES is another key characteristic. It is readily soluble in polar solvents like water, ethanol, and methanol, but largely insoluble in non-polar solvents. This high water solubility is advantageous for its use in aqueous solutions, which are common in laboratory experiments, detergent formulations, and industrial processes. The ability to dissolve easily in water facilitates its incorporation into a wide variety of products and solutions.

Furthermore, MES is known for its excellent calcium soap dispersibility. This property is vital for detergent formulations, as it prevents the formation of insoluble soap scum in hard water, thereby improving cleaning efficiency and preventing residue buildup. Its high detergency and good hard water resistance make it a superior ingredient compared to many traditional dispersants.

The combination of its buffering capacity, solubility, and dispersant properties makes MES a valuable chemical. NINGBO INNO PHARMCHEM CO.,LTD. prides itself on delivering 4-morpholineethanesulfonic acid that meets stringent quality standards, ensuring that researchers and industrial formulators can rely on its consistent performance. Understanding the chemistry of MES unlocks its full potential across diverse applications.
