    Isicelo

    I-Methanesulfonic acid isetshenziswa njenge-catalyst ku-organic reactions okungukuthi i-esterification, i-alkylation kanye ne-condensation reactions ngenxa yokungaguquguquki kwayo kanye nokuncibilika kuzinyibilikisi zemvelo.

    Iphinde ibandakanye ekukhiqizweni kwe-starch esters, i-wax oxidate esters, i-benzoic acid esters, i-phenolic esters, noma i-alkyl esters.

    Ihlangana ne-sodium borohydride phambi kwe-polar solvent tetrahydrofuran ukuze kulungiswe inkimbinkimbi ye-borane-tetrahydrofuran.

    Ithola ukusetshenziswa kumabhethri, ngenxa yokuhlanzeka kwayo nokungabikho kwe-chloride. Embonini yezemithi, isetshenziselwa ukwenziwa kwezithako ezisebenzayo zemithi njenge-telmisartan ne-eprosartan.

    Iwusizo ku-ion chromatography futhi iwumthombo wekhabhoni namandla kwamanye amagciwane e-methylotropic e-gram-negative.Ihilelekile ekuvimbeleni ama-peptide.

    FAQ

     

    Q1: Ngingathola amasampula ohlangothini lwakho?
    Re: Yebo, kunjalo. Singathanda ukukunikeza isampula yamahhala engu-10-1000 g, okuncike emkhiqizweni oyidingayo. Ngempahla, uhlangothi lwakho ludinga ukuthwala, kodwa sizokubuyisela ngemuva kokufaka i-oda lenqwaba.
    Q2: Iyini i-MOQ yakho?
    Re: Ngokuvamile i-MOQ yethu ingu-1 kg, kodwa ngezinye izikhathi nayo iyavumelana nezimo futhi incike emkhiqizweni.
    Q3: Yiziphi izinhlobo zokukhokha ezitholakalayo kuwe?
    Re: Sincoma ukuthi ukhokhe nge-Alibaba, T/T noma L/C, futhi ungakhetha futhi ukukhokha nge-PayPal, Western union, MoneyGram uma inani lingaphansi kuka-USD 3000. Ngaphandle kwalokho, ngezinye izikhathi siyayemukela i-Bitcoin.
    Q4: Kuthiwani ngesikhathi sokuhola?
    Re: Ngenani elincane, izimpahla zizothunyelwa kuwe phakathi kwezinsuku zokusebenza ezingu-1-3 ngemuva kokukhokha.
    Ngenani elikhulu, izimpahla zizothunyelwa kuwe zingakapheli izinsuku zokusebenza ezi-3-7 ngemuva kokukhokha.
    Q5: Ngingathola isikhathi esingakanani izimpahla zami ngemuva kokukhokha?
    Re: Ngenani elincane, sizoletha nge-courier(FedEx, TNT, DHL, njll) futhi ngokuvamile kuzobiza izinsuku ezingu-3-7 eceleni kwakho. Uma u
    bafuna ukusebenzisa umugqa okhethekile noma ukuthunyelwa komoya, singanikeza futhi futhi kuzobiza cishe amasonto angama-1-3.
    Ngobuningi obukhulu, ukuthunyelwa olwandle kuzoba ngcono. Isikhathi sokuthutha, sidinga izinsuku ezingu-3-40, okuncike endaweni yakho.
    Q6: Ithini isevisi yakho yangemva kokuthengisa?
    Re: Sizokwazisa inqubekelaphambili ye-oda, njengokulungiswa komkhiqizo, isimemezelo, ukulandelwa kwezinto zokuhamba, amasiko
    usizo lwemvume, njll.
