CAS 24057-28-1: Pyridinium p-toluenesulfonate

Description: Pyridinium p-toluenesulfonate is an organic compound that serves as a versatile reagent in organic synthesis. It is a salt formed from pyridine and p-toluenesulfonic acid, characterized by its ability to act as a mild acid catalyst in various reactions, particularly in the formation of esters and ethers. This compound is typically a white to off-white crystalline solid, soluble in polar solvents such as water and alcohols, which enhances its utility in aqueous reactions. Its structure features a pyridinium cation and a p-toluenesulfonate anion, contributing to its stability and reactivity. Pyridinium p-toluenesulfonate is often used in the synthesis of complex organic molecules, including pharmaceuticals and agrochemicals, due to its effectiveness in promoting nucleophilic substitutions and facilitating the removal of protecting groups. Additionally, it is valued for its relatively low toxicity compared to other reagents, making it a safer choice in laboratory settings. Proper handling and storage are recommended to maintain its integrity and effectiveness in chemical reactions.
