4-Phenylurazole Usage And Synthesis
Description4-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.
Chemical Propertieswhite to light beige cryst. powder or granules
UsesPrecursor to the Diels-Alder trapping agent, 4-phenyl-1,2,4-triazoline-3,5-dione.1,2,3
Purification MethodsCrystallise 4-phenylurazole from water or 95% EtOH. Dissolve 35g in 80mL of boiling 95% EtOH and on cooling 90-95% is recovered with m 209-210o. It has IR with 1685 and 3120cm-1. [Cookson et al. Org max Synth 51 121 1971, Beilstein 26 I 64, 26 III/IV 540.]
