Isicelo

Burgess dehydrating agent, ekwabizwa ngokuba yiBurgess reagent, yi-methyl N-(triethylaminosulfuryl) carbamate.Inokuphelelwa ngamanzi emzimbeni phantsi kweemeko ezithambileyo kwaye i-ejenti ekhethiweyo yokukhupha amanzi.Isetyenziselwa ukuguqula ii-alcohols zesibini kunye nenqanaba eliphezulu kunye neeproton ezikufutshane kwi-alkenes.

Inokulungiswa ngokusabela kwe-chlorosulfone isocyanate kunye ne-triethylamine kwi-methanol.Ngexesha lokuphelelwa ngamanzi emzimbeni, isulfure ihlaselwa liqela le-hydroxyl, kwaye emva koko ukupheliswa kwe-cis kwenzeka.I-Burgess dehydrating agents ingasetyenziselwa ukudibanisa iikhompawundi ze-isonitrile ezivela kwi-formamide.I-reaction mechanism ifana ne-xanthate yokuphelisa i-xanthate, kwaye i-alkene iphinda ifumaneke ngokuchithwa kwe-cis yemeko yenguqu yendandatho yamalungu amathandathu kwi-molecule.

Ukupakisha kunye noGcino

100g/500g/1kg/25kg okanye njengesicelo;
Iikhemikhali ezingeyongozi, ukugcinwa kwevacuumed kwiqondo lokushisa eliphantsi (2-8 ° C).
(Ukupakishwa okukhethekileyo, akukho kuvalwa. Akukho sithuthi se-cryogenic esifunekayo.)

Ngaphambili: I-Trimethylolpropane trioleate

Okulandelayo: 99% Apixaban CAS 503612-47-3
