N,O-Bis(trimethylsilyl)trifluoroacetamide (BSTFA) (CAS: 25561-30-2) hutumika kwa usanisi wa viambatanishi vya dawa.Inatumika kama kiitikio katika utayarishaji wa ribosidi za pyrimidinone na analogi zinazoonyesha sifa za kuzuia uvimbe.BSTFA iliyo na trimethylchlorosilane imepata matumizi ya kutumika katika kromatografia ya gesi (GC) na spectrometry ya molekuli (MS).BSTFA ni sawa na BSA katika umaalum wa urekebishaji na kuna tafiti kadhaa ambazo zimetumia vitendanishi vyote viwili.Utafiti mmoja ulipata BSTFA bora kuliko BSA katika uthabiti wa bidhaa na mavuno ya derivative.Utafiti mwingine ulilinganisha wafadhili kadhaa wa trimethylsilyl kwa uwekaji wa mwisho wa silika na ikabaini kuwa BSTFA ilikuwa tendaji zaidi kuliko BSA lakini tendaji kidogo kuliko TMCim.BSA na BSTFA zote mbili zilitumiwa kuandaa derivatives ya trimethylsilyl ya pyrimidines na purines.BSTFA hutumika kwa madhumuni ya uchanganuzi au kama kitendanishi cha kemikali kwa usanisi wa molekuli changamano zaidi.Ni kitendanishi cha silylation muhimu katika GC na GC-MS kwa ajili ya kutoa aina mbalimbali za vikundi vya utendaji chini ya hali ndogo.BSTFA ni dawa muhimu ya kati, ambayo inaweza kupunguza polarity ya misombo yenye haidroksi na kuongeza tete, na kufanya sampuli kufaa zaidi kwa uchambuzi wa GC.Kama kitendanishi kidogo cha silanylation kisicho na upande wowote, sio tu ina utendakazi wa juu, uteuzi mzuri, lakini pia ina faida za mavuno ya juu ya mmenyuko na rahisi baada ya matibabu.Pia hutumika kama kizuizi cha DAT na kizuizi cha SLC6A2.Inatumika mara kwa mara kutengeneza asidi ya kaboksili, phenoli, steroids, amini, alkoholi, na alkaloidi na amidi.
