Trifluoromethanesulfonic acid (CF3SO3H), oo loo yaqaan triflic acid, waa aashito aad u firfircoon oo xoog leh oo ka hela isticmaalka ballaaran ee hababka kiimikada iyo warshadaha kala duwan.Waxaa si weyn looga faa'iidaystaa kiciyaye, dareere, iyo reagent sababtoo ah aysiidhkeeda gaarka ah iyo sifooyinka gaarka ah. Mid ka mid ah codsiyada aasaasiga ah ee trifluoromethanesulfonic acid waa kicinta superacid.Waxa loo arkaa mid ka mid ah asiidhyada Brønsted ee ugu xooggan ee la yaqaan, oo ka sarreeya sulfuric, hydrochloric, iyo xitaa fluorosulfuric acid marka loo eego aysiidhka.Aysiidhkan cajiibka ah ayaa u oggolaanaya triflic acid inay kiciso falcelinno kala duwan oo u baahan xaalado aysiidh adag, oo ay ku jiraan esterification, acylation, alkylations, iyo dib-u-habayn.Waxay si gaar ah qiimo u leedahay kor u qaadida falcelinta ku lug leh karbokshanka, maadaama ay dejiso oo ay xoojiso falcelinta.Waxay milmi kartaa tiro balaadhan oo ah xeryahooda noolaha iyo noolaha, taas oo ka dhigaysa mid faa'iido u leh falcelinta ku lug leh solutes polar iyo nonpolar.Intaa waxaa dheer, dabeecadeeda aashitada ah ee xooggan waxay kor u qaadi kartaa milanka iyo caawinta kicinta falcelinta. Isticmaalka kale ee muhiimka ah ee trifluoromethanesulfonic acid waa soosaarka triflate.Triflic acid waxay la falgali kartaa aalkolada, amines, iyo nucleophiles kale si ay u sameeyaan triflates u dhigma (CF3SO3-), kuwaas oo ah kooxo aad u deggan oo shaqeynaya.Triflate waxay u adeegi kartaa kooxo ka tagaya wanaagsan ama waxay dhaqaajiyaan nucleophiles, taasoo awood u siinaysa falcelinno kala duwan oo soo socda sida beddelka nucleophilic, dib-u-habaynta, iyo samaynta curaarta kaarboon-kaarbonFalcelinteeda gaarka ah iyo aysidhka ayaa ka dhigaya reagent qiimo leh samaynta molecules organic adag.Intaa waxaa dheer, waxay soo bandhigi kartaa falcelinta xulashada, taasoo awood u siinaysa inay bartilmaameedsato kooxo gaar ah oo shaqeynaya ama jagooyin ku jira molecule, fududaynta isku-darka isomers gaar ah ama enantiomers. .Taxaddar badbaado oo sax ah, oo ay ku jiraan isticmaalka qalabka ilaalinta iyo ka shaqaynta hawo ku habboon, waa in la raaco si loo yareeyo khatarta. Soo koobid, trifluoromethanesulfonic acid waa asiidh awood leh oo leh codsiyo kala duwan oo ku saabsan hababka kiimikada iyo warshadaha.Aysiidhkeeda aadka u xoogan waxa ay awood u siinaysaa in ay kiciso falcelin balaadhan oo kala duwan, u dhaqanto sida dareere, oo ay ka qayb qaadato samaynta kooxo shaqaynaya oo deggan.Kala duwanaanshaheeda iyo falcelinteeda ayaa ka dhigaysa reagent lama huraan u ah isku dhafka unugyadu organic kakan.Si kastaba ha ahaatee, waa in taxaddar la sameeyaa marka la qabanayo triflic acid, adoo raacaya borotokoolka badbaadada saxda ah si loo hubiyo fayoobida farmashiyaha loogana hortago shilalka.
