Triethylene glycol di-p-tosylate

It acts as a reactive linker due to its two tosylate groups, enabling the formation of rings or extended chains in material science and specialized chemical research. Triethylene glycol di-p-tosylate (TEG-ditosylate) is used mainly as a versatile chemical intermediate and building block in organic synthesis, especially for making complex molecules like crown ethers and cryptands, and as a crosslinking agent in polymer chemistry to create advanced materials with improved mechanical and thermal properties, like protein-resistant surfaces or ion-conductive polymers.
