IR-820 hydrazide 

IR-820 hydrazide is a chemically modified derivative of the near-infrared (NIR) dye IR-820, where a hydrazide functional group (-CONHNH₂) is introduced to enable reactive conjugation.

Applications:

Targeted imaging–conjugation to oxidized polysaccharides, proteins, or antibodies.

Nanoparticle labeling–for in vivo tracking of drug delivery systems.

Theranostics–as a dual imaging/therapy probe in NIR-guided treatments.

Biosensing–coupling with aldehyde-functional substrates for fluorescence-based detection.
