introduction
adipic acid dihydrazide (ADH) is the most suitable hydrazide crosslinking agent. ADH and diacetone acrylamide have been widely used in water-based paint emulsion. ADH is weakly alkaline, solid ADH is directly added to the emulsion may produce coalescence, usually ADH should be dissolved in hot water (poor solubility in cold water) and reused.
use
1. Adiacid dihydrazide bifunctional compound, which can be cross-linked with sodium hyaluronate as a protein drug carrier. It plays a cross-linking role with diacetone acrylamide in the post-crosslinking of water emulsion and water-soluble polymer, such as water-based coatings, adhesives, fibers, plastic film treatment, hair spray, etc., and can also be used as epoxy powder coating curing agent And water-based coating additives, metal deactivators and other polymer additives and water treatment agents, indoor formaldehyde adsorbents and intermediate raw materials.
2. the same bifunctional crosslinking reagent is specially used for aldehydes to generate relatively stable hydrazone links. In particular, it is used to connect glycoproteins, such as antibodies.
3. The same type of bifunctional linker for aldehydes can produce relatively stable hydrazone linkage; for the linkage of carbohydrate proteins, such as antibodies, periodate oxidation reaction occurs at a specific form of position; at pH 5.0, oxidation reaction and coupling reaction can be carried out conveniently, hydrazide derived from low pKa value can avoid competitive reaction through primary amine
4, mainly used for epoxy powder coating curing agent and coating additives, metal deactivator and other polymer additives and water treatment agents
