A difunctional crosslinking agent, adipic acid dihydrazide (ADH) has a melting point of 177–184°C and is moderately soluble in water. Take a look at its structural formula below: After adding ADH to an ammonia-neutralized acrylic emulsion containing DAAM, the emulsion remains stable when stored in one pot.
Adipic acid or hexanedioic acid is the organic compound with the formula (CH2)4(COOH)2. From an industrial perspective, it is the most important dicarboxylic acid: about 2.5 billion kilograms of this white crystalline powder are produced annually, mainly as a precursor for the production of nylon. Adipic acid otherwise rarely occurs in nature, but it is known as manufactured E number food additive E355.
The dihydrazide derivative of adipic acid (Aldrich) is perhaps the most popular homobifunctional hydrazide compound in use. The reagent provides a 10-atom bridge between crosslinked molecules after conjugation.
The invention discloses a synthesis method of adipic acid dihydrazide. The method is characterized by taking adipic acid and hydrazine hydrate as raw materials, and synthesizing adipic acid...
Commercially available homobifunctional hydrazide compounds (i.e., those which have a hydrazide group at each end) include carbohydrazide (MW 90.1) and adipic acid dihydrazide (ADH, MW 174.2). These bis-hydrazide compounds could be used in a single reaction to crosslink and polymerize prepared (aldehyde-containing) sugars or polysaccharides. However, they are more frequently used to modify and conjugate molecules in two stages, either homobifunctionally or heterobifunctionally.

Adipic acid dihydrazide (ADH) is a chemical used for cross-linking water-based emulsions. It can also be used as a hardener for certain epoxy resins. ADH is a symmetrical molecule with a C4 backbone and the reactive group is C=ONHNH2. Dihydrazides are made by the reaction of an organic acid with hydrazine.
Adipic Acid Dihydrazide is used as chain extender in the preparation of waterborne polyurethane binders and secondly as crosslinker in waterbased coatingsused as chain extender in the preparation of waterborne polyurethane binders and secondly as crosslinker in waterbased coatings.
adipic acid dihydrazide (ADH), derived from adipic acid, sebacic acid dihydrazide (SDH), valine dihydrazide (VDH), derived from the amino acid valine, and isophthalic dihydrazide (IDH). The aliphatic R group can be of any length. For example, when R group is just carbon, the resulting compound is carbodihydrazide (CDH), the fastest dihydrazide.
Adipic Acid Dihydrazide, also known as ADH or Adipohydrazide, can be used as a hardener for epoxy resins and for cross-linking water-based emulsions. Ungraded products supplied by Spectrum are indicative of a grade suitable for general industrial use or research purposes and typically are not suitable for human consumption or therapeutic use.

Adipic Acid Dihydrazide is a chemcial intermediate and specialty chemical often used in adhesive and coating-manufacturing applications. It offers amino- and keto-functionality at either end of the molecule which makes it an excellent cross-linking agent for water-based emulsions.
Adipic acid is also used to manufacture plasticizers and lubricant components. Food grade adipic acid is used as a gelling aid, an acidulant, and as a leavening and buffering agent. TCC ships adipic acid throughout the continental United States with one (1) week lead time. Call (401) 360-2800 for details.
Adipic acid dihydrazide is a homobifunctional cross-linking reagent specific for aldehydes resulting in relatively stable hydrazone linkages. Adipic acid dihydrazide is typically, used in the linking of glycoproteins, such as antibodies, in a site specific fashion following periodate oxidation.

Adipic Acid Dihydrazide (ADH) is widely used as cross-linker in waterborne acrylic emulsions.
covalent bonds between the dihydrazide and carbonyl groups at the treated polymer substrate surface. Our system of interest consists of an acrylic latex containing diacetone acrylamide pendant groups (Figure 1A) on the polymer backbone that reacts with an adipic dihydrazide di-functional cross-linker (Figure 1B).
Adipic acid dihydrazide (ADH) is a chemical used for cross-linking water-based emulsions. It can also be used as a hardener for certain epoxy resins. ADH is a symmetrical molecule with a C4 backbone and the reactive group is C=ONHNH 2. Dihydrazides are made by the reaction of an organic acid with hydrazine.
Therefore, adipic acid dihydrazide (ADH) has been coupled to HRP with the use of the periodate method reaction to provide the necessary amino group for the preparation of hapten enzyme conjugate with the use of the carbodiimide method.
