P-TOLUENESULFONIC ACID N-BUTYL ESTER CAS:778-28-9

p-Toluenesulfonic acid n-butyl ester, or butyl p-toluenesulfonate (C11H14O3S), is an important aromatic sulfonate with versatile applications in organic chemistry and industrial processes. Characterized by the presence of a butyl group (-C4H9) linked to the sulfonate moiety of p-toluenesulfonic acid, this compound typically appears as a clear, colorless to pale yellow liquid that is soluble in various organic solvents, which enhances its utility in synthetic applications. One of the primary uses of butyl p-toluenesulfonate lies in its function as a reagent in organic synthesis. It acts as an electrophilic agent in condensation reactions, particularly in the esterification of alcohols and carboxylic acids. The presence of the butyl group imparts increased hydrophobic characteristics to the resulting esters, making them suitable for various applications in pharmaceuticals and agrochemicals. Additionally, butyl p-toluenesulfonate serves as a coupling agent in polymerization reactions, where it facilitates the formation of covalent bonds between different monomers. Its ability to enhance the compatibility of disparate materials makes it invaluable in developing new polymers with tailored properties. Moreover, due to its strong acidity, it can be utilized as an acid catalyst in several reactions, promoting the formation of desired products while minimizing side reactions. Despite its beneficial properties, safety precautions should be observed when handling butyl p-toluenesulfonate, as it can irritate the skin, eyes, and respiratory system. Proper personal protective equipment and adequate ventilation are essential during its use. In summary, p-toluenesulfonic acid n-butyl ester is a multifunctional compound that plays a crucial role in organic synthesis, polymer science, and various chemical manufacturing processes, demonstrating its importance within the broader context of industrial chemistry.
