N,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA) CAS 25561-30-2 99% BSTFA + 1% TMCS no GC Factory

N, O-Bis (trimethylsilyl) trifluoroacetamide (BSTFA) (CAS: 25561-30-2) hoʻohana ʻia no ka hoʻohui ʻana i nā mea waena lāʻau.Hoʻohana ʻia e like me ka reactant i ka hoʻomākaukau ʻana i nā ribosides pyrimidinone a me nā analogs e hōʻike ana i nā waiwai anti-tumor.Ua loaʻa i ka BSTFA me ka trimethylchlorosilane ka noi e hoʻohana ʻia i ka chromatography kinoea (GC) a me ka mass-spectrometry (MS).Ua like ka BSTFA me ka BSA ma ke kiko'ī o ka hoʻololi ʻana a he nui nā haʻawina i hoʻohana i nā reagents ʻelua.Ua ʻike ʻia kahi haʻawina ʻoi aku ka maikaʻi o ka BSTFA ma mua o ka BSA i ka paʻa ʻana o ka huahana a me ka hua o ka derivative.Ua hoʻohālikelike kekahi haʻawina i kekahi mau mea hāʻawi trimethylsilyl no ka hoʻopau ʻana i ka silica a ʻike ʻia ʻoi aku ka ʻoi aku o ka BSTFA ma mua o ka BSA akā ʻoi aku ka liʻiliʻi ma mua o TMCim.Ua hoʻohana ʻia ʻo BSA a me BSTFA e hoʻomākaukau i nā derivatives trimethylsilyl o nā pyrimidines a me nā purines.Hoʻohana ʻia ʻo BSTFA no nā kumu analytical a i ʻole ma ke ʻano he reagent kemika no ka synthesis o nā molekala paʻakikī.He mea hoʻohana i ka silylation reagent ma GC a me GC-MS no ka derivatization o kahi ākea o nā hui hana ma lalo o nā kūlana haʻahaʻa.He mea koʻikoʻi ka BSTFA i waena o nā lāʻau lapaʻau, hiki ke hōʻemi i ka polarity o nā pūhui hydroxy-containing a hoʻonui i ko lākou volatility, e hana i nā laʻana i kūpono no ka loiloi GC.Ma ke ʻano he reagent silanylation haʻahaʻa, ʻaʻole ia he kiʻekiʻe reactivity, koho maikaʻi, akā loaʻa pū kekahi i nā pono o ka hopena hopena kiʻekiʻe a me ka maʻalahi ma hope o ka mālama ʻana.Hoʻohana ʻia ia e like me DAT inhibitor a me SLC6A2 inhibitor.Hoʻohana mau ʻia ia e derivatize carboxylic acids, phenols, steroids, amines, alcohols, and alkaloids and amides.
