m-PEG2-Tos features a para-toluensulfonate leaving group flanked by a short ethylene glycol spacer, enabling efficient conjugation in bioorthogonal workflows. This bench-stable derivative facilitates rapid coupling with nucleophiles under mild conditions, delivering clean reaction profiles and high yields.
m-PEG2-Tos serves as a versatile bifunctional linker for conjugation and solid-phase synthesis, combining the solubility and stability of a short PEG spacer with a readily cleavable tosyl leaving group. It facilitates efficient amine functionalization and enables clean deprotection under mild conditions, making it ideal for peptide, oligonucleotide, and small-molecule derivatization workflows.
