Khoom Description
(5R-cis)-Toluene-4-sulfonic Acid 5-(2,4-Difluorophenyl)-5-[1,2,4]triazol-1-ylmethyltetrahydrofuran{{ 12}}ylmethyl Ester tseem hu ua TMSOTf, uas yog ib qho kev siv tshuaj reagent hauv organic synthesis. Nws yog cov hmoov dawb dawb dawb thiab yooj yim soluble hauv acetonitrile thiab dimethyl sulfoxide. Nws yog soluble hauv methanol. Nws yuav luag insoluble hauv dej.
Posaconazole Impurity 53 yog khaus thiab corrosive rau ntawm daim tawv nqaij, qhov muag thiab ua pa ib ntsuj av. Thaum siv nws, hnav hnab looj tes tiv thaiv tsim nyog, tsom iav kev nyab xeeb thiab hnav khaub ncaws tiv thaiv kom tsis txhob muaj kev sib cuag.
