N-t-Boc-Aminooxy-PEG4-N-(PEG2-Propargyl) is a click chemistry crosslinker. The propargyl group is reactive with azide-containing compounds or biomolecules through copper catalyzed Click Chemistry to yield a stable triazole linkage. t-Boc-aminooxy can be deprotected under mild acidic conditions. The hydrophilic PEG linker improves solubility in aqueous media.

Brevetoxins (PbTx) are a class of cyclic polyether compounds produced by certain algae such as Karenia brevis. K. brevis can produce Brevetoxins in large quantities during an algae bloom which then pose a major health threat and are important to monitor and mitigate. Brevetoxins are the causative agent of Neurotoxic Shellfish Poisoning (NSP).
