Tetraethylene glycol di(p-toluenesulfonate) was used in the preparation of donor-spacer-acceptor podand system, dual channel fluorosensor for Li+, Mg2+ and Ca2+.
Bis-Tos-PEG4 serves as a versatile bifunctional linker for conjugation and polymer synthesis, enabling efficient coupling of biomolecules and small molecules. Its PEG4 spacer provides enhanced solubility and reduced aggregation, while the Tosyl (Tos) groups offer reliable activation for nucleophilic substitution under mild conditions. The molecule demonstrates excellent bench stability and clean reaction profiles, facilitating straightforward purification and integration into established synthetic workflows.
