Dihydrazide adipate (ADH) is the most suitable hydrazide cross-linking agent, ADH and diacetone acrylamide in water paint emulsion has been widely used. ADH is weakly alkaline, the solid ADH directly added to the emulsion may produce coalescence, ADH should usually be dissolved in hot water (cold water solubility is not good) before use. Chemical properties white crystal. Melting point: 180-182℃. Colorless and transparent, no visible insoluble matter. Use dionate dihydrazide bifunctive compound can be cross-linked with sodium hyaluronate as a protein drug carrier.
And diacetone acrylamide in water emulsion and water soluble polymer crosslinked after crosslinking role, such as coating, adhesive, fiber and plastic processing, hair gel, etc., also can be used as a curing agent and coating epoxy powder coating additives, metal attenuated agent and other polymer additives and water treatment agent, indoor formaldehyde adsorbent materials and intermediates. Use as a double function crosslinking reagent, especially for aldehydes, to form relatively stable hydrazone links. In particular, it is used to link glycoproteins, such as antibodies.
It is used as a isotype bifunctional linker for aldehydes and can produce relatively stable hydrazone connection. Used for the linkage of carbohydrate proteins, such as antibodies, to undergo periodate oxidation at a specific site; At pH5.0, the oxidation reaction and coupling reaction can be carried out conveniently. The hydrazide derived from low pKa value can avoid competing reaction through primary amine. It is mainly used as curing agent for epoxy powder coatings and coating additives.
