N,O-Bis (trimethylsilyl) trifluoroacetamide (BSTFA) CAS 25561-30-2 99% BSTFA + 1% TMCS ee Warshada GC

N,O-Bis (trimethylsilyl) trifluoroacetamide (BSTFA) (CAS: 25561-30-2) waxaa loo isticmaalaa isku dhafka dhexdhexaadiyeyaasha daawooyinka.Loo isticmaalo fal-celin ahaan diyaarinta pyrimidinone ribosides iyo analogs kuwaas oo muujinaya guryaha lidka ku ah buro.BSTFA oo leh trimethylchlorosilane waxay heshay codsi loo isticmaalo chromatography gaaska (GC) iyo mass-spectrometry (MS).BSTFA waxay la mid tahay BSA gaar ahaan wax ka beddelka waxaana jira daraasado dhowr ah oo isticmaalay labada reagen.Hal daraasad ayaa lagu ogaaday in BSTFA ay ka sarreyso BSA marka loo eego xasilloonida badeecada iyo wax-soo-saarka soosaarka.Daraasad kale ayaa is barbardhigtay dhowr deeq-bixiyeyaal trimethylsilyl si loo dhammeeyo silica waxaana lagu arkay in BSTFA ay ka falcelis badan tahay BSA laakiin ka falcelis yar TMCim.Labada BSA iyo BSTFA ayaa loo isticmaalay diyaarinta trimethylsilyl derivatives ee pyrimidine iyo purines.BSTFA waxaa loo isticmaalaa ujeeddooyin gorfayn ama sidii reagen kiimiko ah oo loogu talagalay soo saarista molecules kakan.Waa reagent silylation faa'iido u leh GC iyo GC-MS ee kala saarista kooxo badan oo shaqeynaya oo ku jira xaalado khafiif ah.BSTFA waa dhexdhexaad dawo oo muhiim ah, kaas oo yarayn kara polarity ee xeryahooda hydroxy-ku jira oo kordhin kara isbeddelkooda, samaynta muunado ku habboon falanqaynta GC.Sida reagent silanylation dhexdhexaad ah oo khafiif ah, ma aha oo kaliya waxay leedahay reactivity sare, xulashada wanaagsan, laakiin sidoo kale waxay leedahay faa'iidooyinka dhalidda falcelinta sare iyo daaweynta fudud ka dib.Waxa kale oo loo istcimaalayaa sida DAT inhibitor iyo SLC6A2 inhibitor ah.Waxaa si joogta ah loo isticmaalaa in laga saaro asiidhyada karboksilic, phenols, steroids, amines, alcohols, iyo alkaloids iyo amides.
