4-Methylaminophenol sulfate Siv Thiab Synthesis

Kev piav qhia	Metol muaj nyob rau hauv cov neeg tsim yeeb yaj kiab dub thiab dawb thiab ua rau muaj kev sib cuag dermatitis hauv cov kws yees duab.
Chemical Properties	Dawb crystalline hmoov
Siv	Tus tsim tawm yees duab; dyeing furs.
Siv	Metol yog tus tsim duab dub thiab dawb; dyeing plaub hau; raws li pigment nyob rau hauv cov plaub hau dyes.
Siv	4-(Methylamino) phenol sulfate yog tus kws yees duab tsim siv hauv kev yees duab dub thiab dawb. Nws kuj tseem siv los ua cov suab nrov tsim tawm hauv cov neeg ua haujlwm tsim. Tsis tas li ntawd, nws yog siv nyob rau hauv oxidative plaub hau dye formulations.
Siv	4-methylaminophenol sulfate yog siv los ua tus tsim kho duab thiab xim plaub.
Txhais	ChEBI: sulfate ntsev ntawm 4-methylaminophenol.
Kev piav qhia dav dav	Off-dawb crystalline khoom. Sensitive rau lub teeb.
Cua & Dej Reactions	Dej soluble.
Reactivity Profile	Nyob rau hauv aqueous tov behaves raws li ib tug acid. Cov ntaub ntawv hauv pawg no feem ntau yog soluble hauv dej. Cov kev daws teeb meem muaj qhov nruab nrab ntawm cov hydrogen ions thiab muaj pH tsawg dua 7.0. Lawv react li acids rau neutralize bases. Cov neutralizations ua kom sov, tab sis tsawg dua los yog tsawg dua yog tsim los ntawm neutralization ntawm inorganic acids, inorganic oxoacids, thiab carboxylic acid. Lawv feem ntau tsis hnov mob li oxidizing tus neeg saib xyuas lossis txo cov neeg ua haujlwm tab sis tus cwj pwm zoo li no tsis yooj yim sua. Ntau ntawm cov tebchaw no catalyze cov tshuaj tiv thaiv organic.
Hazard	Qhov muag thiab tawv nqaij irritant.
Hluav Taws Xob	Cov ntaub ntawv flash point rau 4-Methylaminophenol sulfate tsis muaj tab sis 4-Methylaminophenol sulfate yog tej zaum combustible.
Tiv tauj cov tshuaj tsis haum	Metol muaj nyob rau hauv cov neeg tsim yeeb yaj kiab dub thiab dawb thiab ua rau muaj kev sib cuag dermatitis hauv cov kws yees duab.
Txoj Kev Purification	Crystallize tus yees duab tsim los ntawm H2O ( koob m 250-260o) (nws solubility yog 5% ntawm 20o thiab 17% ntawm 100o) los yog MeOH. Nws yog siv los txiav txim Ag. [Palit et al. Indian J Chem, Sect B 28 64 1989.]
