Application
1. Used as formaldehyde trapping agent to remove formaldehyde remaining in fabrics after finishing by 2D-resin, KB-resin, urea-formaldehyde resin, melamine-formaldehyde resin, etc. It is also used as an intermediate of fine chemicals, used in the manufacture of resins, plasticizers, spray paint, adhesives, etc.
2. used as formaldehyde capture agent, intermediate of fine chemicals, also used in the manufacture of resins and formulation of plasticizers, spray paint, adhesives and other uses for the synthesis of chiral microporous materials prepared from non-chiral precursors;
3. for the preparation of aryl as well as heteroaryl N-acyl ureas by microwave-assisted palladium catalyzed carbonylation reaction; for the synthesis of a highly water-soluble peptide based on human neutrophil elastase inhibitors; for the synthesis of antibacterial heterocycles formed by cyanoacetylation reacti
ons; for Pd-catalyzed C-N bond formation with heteroaryl toluene sulfonates; for the activation of streptavidin Oxidative amidation reactions
