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.

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.

Other Notes

Note that the hydrazone bond may be stabilized by selective reduction using, for example, sodium cyanoborohydride.

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
