설명

애플리케이션

1,4-Phenylene diisocyanate (PPDI) can be used as:

• A reactant to synthesize high yield polymers via criss-cross addition polymerization reaction with alkyl aldazines in pyridine.
• An organic building block to prepare adamantyl-containing diurea and thiourea derivatives applicable as potent mammalian and human soluble epoxide hydrolase inhibitors.
• A coupling agent to synthesize polyethylene glycol (PEG)/silica composite material using dibutyltin dilaurate (DBTDL) as a catalyst.

It can also be used:

• As a cross-linking reagent to investigate the mechanism of enzyme immobilization on silanized surfaces.
• In the synthesis of the dipodal bis-urea receptor, a selective receptor for hydrogen sulfate.
• In the deposition of polyurea resists films via molecular layer deposition.
