Taw qhia
5-chloro-6-methoxyniacin yog cov organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Khoom: 5-Chloro-6-methoxynicotinic acid yog dawb los yog dawb crystalline hmoov. Nws yog soluble hauv cov kuab tshuaj organic xws li ethanol, acetone, thiab methanol ntawm chav tsev kub, thiab muaj solubility tsawg hauv dej. Nws muaj qee yam nicotinic zog thiab methoxy yam ntxwv.
Txoj kev: Lub synthesis ntawm 5-chloro-6-methoxynicotinic acid feem ntau tau los ntawm chlorination ntawm methoxynicotinic acid. Ib txoj kev npaj ntau yog los ua cov tshuaj methoxyniacin nrog thionyl chloride los tsim 5-chloro-6-methoxyniacin.
Cov ntaub ntawv kev nyab xeeb: 5-Chloro-6-methoxyniacin feem ntau muaj kev nyab xeeb raws li kev siv ib txwm siv, tab sis tseem yuav tsum tau ceev faj kom tsim nyog. Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij, qhov muag, thiab kab mob ua pa kom tsis txhob muaj qhov khaus lossis tsis xis nyob. Cov cuab yeej tiv thaiv tsim nyog xws li hnab looj tes (lab) hnab looj tes, tsom iav, thiab lub npog ntsej muag yuav tsum hnav thaum siv. Yuav tsum tau saib xyuas kom tsis txhob muaj teeb meem tshwm sim los ntawm hluav taws xob thiab hluav taws xob zoo li qub thaum khaws cia thiab tuav.
