Phenylhydrazine CAS 100-63-0 Purity > 99.0% (GC)

Phenylhydrazine (CAS: 100-63-0), tseem hu ua Hydrazinobenzene.Nws yog thawj zaug ua tiav los ntawm German organic chemist Hermann-Emil-Fischer hauv xyoo 1875 thiab yog thawj cov khoom siv hydrazine derivatives.Nws tuaj yeem yooj yim raug oxidization hauv huab cua thiab pom cov xim av tsaus lossis xim liab.Phenylhydrazinefeem ntau yuav siv tau los ua intermediates ntawm cov organic dyes, tshuaj thiab tshuaj tua kab.Nws kuj tseem siv tau los ua cov organic intermediates rau kev sib txuas ntawm pyrazoline, triazole, thiab indole;Nws kuj tuaj yeem siv los ua cov xim nruab nrab xws li disazo dye intermediates xws li 1-phenyl-3-methyl-5-pyrazolone thiab lwm yam;Nws kuj tseem siv tau los ua cov tshuaj intermediates rau kev npaj ntawm antipyretic, analgesic, anti-inflammatory tshuaj xws li antipyrine thiab aminopyrine, thiab lwm yam;nws kuj tseem siv tau los ua cov tshuaj yees duab (photosensitive dye);Phenylhydrazine tseem yog cov khoom siv raw rau kev tsim cov tshuaj tua kab "imputed phosphorus";Phenylhydrazine yog siv los ua tus stabilizer rau cov khoom tawg;raws li ib tug reagent rau aldehydes, ketones thiab suab thaj nyob rau hauv tshuaj ntsuam xyuas;nyob rau hauv cov organic synthesis.Reagents rau Npaj Cov Kab Mob Tsiaj.Siv nyob rau hauv lub synthesis ntawm dyes thiab lwm yam organic tshuaj.Feem ntau siv hauv kev tsim cov azoic coupling tivthaiv AS-G.Phenylhydrazine koom nrog hauv Fischer indole synthesis los npaj indoles, uas pom daim ntawv thov raws li intermediates hauv cov kws tshuaj tshwj xeeb rau cov tshuaj tryptamine.Hauv kev tshuaj ntsuam chemistry, nws yog siv los sib txawv thiab cais cov suab thaj los ntawm kev tsim phenyhydrazones.Nws yog siv los ua N-tiv thaiv reagent thiab rau cleavage ntawm phthaloyl pawg.Phenylhydrazine kuj tseem siv los ua cov tshuaj analytical reagent.Nws kuj yog ib qho tseem ceeb reagent rau kev txheeb xyuas cov pab pawg carbonyl thiab tuaj yeem siv los txheeb xyuas cov aldehydes, ketones thiab carbohydrates.Nws tuaj yeem cuam tshuam nrog benzaldehyde los tsim phenylhydrazine.Cov txheej txheem ntawm nws cov kev npaj yog los ntawm cov tshuaj tiv thaiv ntawm aniline thiab sodium nitrite nyob rau hauv qhov kev txiav txim ntawm hydrochloric acid rau tiam diazonium ntsev uas yog ces txo los ntawm sulfite / sodium txo kom tau nws.Acid nag lossis daus tuaj yeem tsim phenylhydrazine hydrochloride nrog kev ua haujlwm nruab nrab ntawm phenylhydrazine.
