CAS 37860-51-8: Tetraethylene glycol ditosylate

Description: Tetraethylene glycol ditosylate, with the CAS number 37860-51-8, is an organic compound that serves as a versatile reagent in organic synthesis, particularly in the field of polymer chemistry and bioconjugation. It is characterized by the presence of two tosyl (tosylate) groups attached to a tetraethylene glycol backbone, which enhances its reactivity and solubility in various solvents. The tosylate groups are good leaving groups, making the compound useful for nucleophilic substitution reactions. Tetraethylene glycol ditosylate is typically a colorless to pale yellow liquid or solid, depending on its purity and form. It is hygroscopic, meaning it can absorb moisture from the air, which can affect its stability and reactivity. This compound is often used in the synthesis of complex molecules, including pharmaceuticals and polymers, due to its ability to facilitate the formation of ether linkages. Safety precautions should be taken when handling this compound, as it may pose health risks if inhaled or ingested, and appropriate protective equipment should be used.
