3-Methoxyphenylhydrazine hydrochloride yog cov organic compound nrog cov tshuaj formula C7H10ClN2O. Nws yog dawb los yog daj me ntsis crystalline khoom.
Kev siv lub ntsiab ntawm cov tshuaj no yog ib qho nruab nrab hauv cov organic synthesis. Nws tuaj yeem siv los tsim cov khoom siv roj ntsha lom neeg, xws li tshuaj lossis tshuaj tua kab. Tsis tas li ntawd, 3-Methoxyphenylhydrazine hydrochloride tuaj yeem siv los ua cov khoom siv hluavtaws rau cov nroj tsuag kev loj hlob regulators lossis dyes.
Txoj kev npaj 3-Methoxyphenylhydrazine hydrochloride feem ntau yog ua rau 3-methoxyphenylhydrazine nrog hydrochloric acid. Ua ntej, 3-methoxyphenylhydrazine reacted nrog acetic acid nyob rau hauv acidic tej yam kev mob muab 3-methoxyphenylhydrazine acetate, uas yog ces reacted nrog hydrochloric acid muab 3-Methoxyphenylhydrazine hydrochloride.
Hais txog kev nyab xeeb cov ntaub ntawv, 3-Methoxyphenylhydrazine hydrochloride yog cov tshuaj lom. Kev cuam tshuam rau cov tshuaj yuav ua rau muaj teeb meem xws li khaus qhov muag thiab khaus tawv nqaij. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ntsuas kev nyab xeeb tsim nyog thaum tuav thiab siv, xws li hnav hnab looj tes tiv thaiv, tsom iav thiab qhov ncauj qhov ntswg. Tsis tas li ntawd, tsis txhob sib cuag nrog cov oxidizing muaj zog kom tsis txhob muaj kev phom sij txaus ntshai.
