| Application: | Adipic acid dihydrazide has been used: • in the preparation of reactive premix to synthesize the porous biomaterial • for the crosslinking of methacrylated chondroitin sulfate (MA-CS) coating using carbodiimide-based chemistry for the production and characterization of methacrylated chondroitin sulfate magnetic nanoparticles (MA-CS MNPs) • for the covalent labeling of rhamnolipids, pyochelin, and vancomycin with Abberior STARNHS ester dye |
| Biochem/physiol Actions: | Adipic acid dihydrazide (ADH) is a low molecular weight compound that comprises a hydrazide group at each end. This leads to the supply of extra adsorption sites for heavy metals that maintain or elevate the adsorption capacities of the cross-linked adsorbents. ADH is used as a crosslinker in various fields, like making mechanical latexes films and injectable oxidized hyaluronic acid hydrogel. |
| General description: | Adipic acid dihydrazide is a homobifunctional cross-linking reagent that is specific for aldehydes. This results in relatively stable hydrazone linkages. Adipic acid dihydrazide is generally used in the linking of glycoproteins, like antibodies, in a site-specific fashion following periodate oxidation. Oxidation and coupling may be performed at pH 5.0 due to the low pKa of the hydrazide which avoids competition by primary amines. |
| Other Notes: | Note that the hydrazone bond may be stabilized by selective reduction using, for example, sodium cyanoborohydride. |
