Triethylene glycol ditosylate

Description:

Triethylene glycol ditosylate, with the CAS number 19249-03-7, is an organic compound characterized by its structure, which includes two tosyl (p-toluenesulfonyl) groups attached to a triethylene glycol backbone. This compound is typically a colorless to pale yellow liquid and is known for its high solubility in organic solvents, making it useful in various chemical applications. It exhibits properties such as being hygroscopic and having a relatively high boiling point. Triethylene glycol ditosylate serves as a versatile reagent in organic synthesis, particularly in the formation of glycosidic bonds and as a protecting group for alcohols. Its tosyl groups enhance its reactivity, allowing it to participate in nucleophilic substitution reactions. Additionally, it is important to handle this compound with care, as it may pose health risks upon exposure. Overall, triethylene glycol ditosylate is valued in synthetic chemistry for its functional versatility and reactivity.
