Azide-PEG3-OH is a bifunctional molecule with an azide group, primary alcohol, and a hydrophilic PEG3 linker in between.

BDP 558/568 is a borondipyrromethene fluorophore with absorption and emission spectra close to Cyanine3. This is an azide derivative for сlick chemistry.

A hydrophilic bifunctional linker with azide and tetrazine function groups flanking PEG3 (triethylene glycol) spacer.

BDP 558/568 is a borondipyrromethene dye with yellow emission. The dye as a carboxylic acid can be used in peptide synthesis (after appropriate activation of the carboxylic group).

PEG4 amine azide is a bifunctional linker with amine and azide functional groups. It is based on a tetraethyleneglycol core. The length of the PEG4 linker is 1.4 nm.

PEG4 diazide is a homobifunctional linker with two azide groups. It can be used for the synthesis of dimeric molecules with a hydrophilic core by click chemistry.

Bifunctional tetraethylene glycol with terminal carboxyl and azido groups.

A bifunctional reagent containing the azide group and hydrazide function. It reacts with aldehydes and ketones. The azide group can then be coupled with various alkynes via CuAAC reaction.

Azide-PEG4-OH is a bifunctional molecule with an azide group, primary alcohol, and a hydrophilic PEG4 linker in between.

A hydrophilic bifunctional linker with azide and NHS ester function groups flanking PEG6 (hexaethylene glycol).
