1-methylpyridinium-2-sulfonate

Description:
1-Methylpyridinium-2-sulfonate is an organic compound characterized by its pyridinium structure, which features a nitrogen atom in a six-membered aromatic ring. This compound is a quaternary ammonium salt, where the nitrogen is positively charged, contributing to its solubility in polar solvents, particularly water. The sulfonate group (-SO3) enhances its ionic character, making it a good candidate for various applications in organic synthesis and as a reagent in chemical reactions. It is often used in electrochemistry and as a phase-transfer catalyst due to its ability to facilitate the transfer of ions across interfaces. The presence of the methyl group at the 1-position of the pyridine ring influences its reactivity and solubility properties. Additionally, 1-methylpyridinium-2-sulfonate is known for its stability under a range of conditions, although it should be handled with care due to its ionic nature. Overall, this compound serves as a valuable tool in both academic and industrial chemistry settings.
