TCO-carbonylamino-benzamido-PEG3 acid
This product is a heterobifunctional linker featuring a trans-cyclooctene (TCO) group, a benzamido unit, a PEG3 spacer, and a terminal carboxylic acid. The TCO enables ultrafast, copper-free click chemistry with tetrazines via IEDDA ligation, while the carboxyl group couples efficiently with amines or activated esters. The PEG3 chain specifically provides solubility and moderate spacing, making this reagent valuable for bioconjugation, probe development, and drug delivery.
