Allyl p-toluenesulphonate serves as a key intermediate in the synthesis of specialty chemicals, particularly in the development of allylic compounds and sulfonate derivatives. It is employed in polymer science as a crosslinking agent or monomer modifier due to its reactive double bond. In pharmaceuticals, it aids in prodrug design and controlled-release formulations. Its tosylate group also facilitates nucleophilic displacement reactions in organic synthesis.
