Sodium p-toluenesulfonate

Description:

Sodium p-toluenesulfonate, with the CAS number 657-84-1, is an organic sodium salt derived from p-toluenesulfonic acid. It appears as a white to off-white crystalline powder and is highly soluble in water, making it useful in various applications. This compound is characterized by its sulfonate group, which imparts strong ionic properties, enhancing its solubility and reactivity. Sodium p-toluenesulfonate is commonly used as a reagent in organic synthesis, particularly in the preparation of esters and in the activation of alcohols for nucleophilic substitution reactions. Additionally, it serves as a surfactant and a stabilizing agent in various formulations. Its low toxicity and stability under standard conditions make it a favorable choice in laboratory and industrial settings. However, like many chemical substances, it should be handled with care, following appropriate safety guidelines to avoid potential hazards.
