E20200, or potassium sorbate, is a vital preservative that offers numerous benefits across food, cosmetic, and pharmaceutical applications. Its ability to inhibit microbial growth helps maintain product safety and prolong their shelf life, making it an essential ingredient in many consumer goods.

NMR spectroscopy is a powerful analytical technique that provides detailed information about the structure, dynamics, and environment of molecules. It relies on the alignment of nuclear spins in a magnetic field and their subsequent relaxation to provide a spectrum. When non-deuterated solvents, such as methanol or ethanol, are used, the protons (¹H) in the solvent can contribute to the NMR signal, complicating the spectra and obscuring the information about the solute being studied. In contrast, deuterated solvents, such as deuterated chloroform (CDCl₃) or deuterated dimethyl sulfoxide (DMSO-d₆), contain fewer protons, markedly reducing interference and enhancing the clarity of the resulting spectrum.
