Description and Uses
4-phenylurazole is a kind of laboratory chemicals used for the manufacturing of some substances. It can be used as the precursor to the Diels-Alder trapping agent, 4-phenyl-1, 2, 4-triazoline-3, 5-Dione. Its derivative, azo dyes, has wide applications in dyes industry. In the presence of phosgene, terephthaloyl chloride and epichlorohydrin, it can be polymerized to yield insoluble polymer.
Precursor to the Diels-Alder trapping agent, 4-phenyl-1,2,4-triazoline-3,5-dione.1,2,3
