개요
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.화학적 성질

Precursor to the Diels-Alder trapping agent, 4-phenyl-1,2,4-triazoline-3,5-dione.1,2,3일반 설명
4-Phenylurazole undergoes oxidation in the presence of NO2-N2O4 to yield 4-phenyl-1,2,4-trizoline-3,5-dione. It undergoes acetylation reaction with excess acetyl chloride in N,N-dimethylacetamide solution. It polymerizes in the presence of phosgene, terephthaloyl chloride and epichlorohydrin to yield insoluble polymer. It is precursor to the Diels-Alder trapping agent, 4-phenyl-1,2,4-triazoline-3,5-dione. This urazole was recently demonstrated in the traceless, chemoselective labeling of peptides and proteins through electrochemical tyrosine-click (e-Y-CLICK) chemistry.Purification Methods
Crystallise 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.]참고 문헌
