    Isicelo

    I-Methanesulfonic acid isetyenziswa njenge-catalyst kwi-organic reactions oko kukuthi i-esterification, i-alkylation kunye ne-condensation reactions ngenxa yendalo yayo engaguquguqukiyo kunye nokunyibilika kwizinyibilikisi eziphilayo.

    Ikwabandakanyeka ekuveliseni i-starch esters, i-wax oxidate esters, i-benzoic acid esters, i-phenolic esters, okanye i-alkyl esters.

    Isabela nge-sodium borohydride phambi kwe-polar solvent tetrahydrofuran ukulungiselela i-borane-tetrahydrofuran complex.

    Ifumana isicelo kwiibhetri, ngenxa yokuhlanzeka kwayo kunye nokungabikho kwekloridi. Kumashishini amayeza, isetyenziselwa ukwenza izithako ezisebenzayo zamayeza njenge-telmisartan kunye ne-eprosartan.

    Iluncedo kwi-ion chromatography kwaye ngumthombo wekhabhoni kunye namandla kwezinye iibhaktheriya ze-methylotropic zegram-negative.Ibandakanyeka ekukhuselweni kweepeptide.
