2-methylsulfonyl-4-trifluoromethylbenzoic acid (MSTFA) ke motsoako o nang le lintho tse latelang:

Ponahalo: MSTFA ke mokelikeli o se nang 'mala ho isa ho o mosehla o khanyang.

Sollubility: E qhibiliha ka har'a metsoako e mengata ea tlhaho, joalo ka dimethylformamide, acetonitrile, le methanol.

Botsitso: MSTFA ke motsoako o batlang o tsitsitse, empa o ka bola le ho hlahisa likhase tse chefo kapa lintho tse senyang nakong ea polokelo kapa ho futhumatsa.

MSTFA e sebelisoa haholo ho sekaseka karabelo ea ho tsoa ho k'hemistri, ka lits'ebetso tse ikhethileng tse kenyelletsang:

Tlhahlobong ea khase ea chromatography-mass spectrometry (GC-MS), MSTFA e sebelisoa e le ntho e tsoang ho lisampole tsa tlhahlobo ea pele, e ka fetolelang metsoako e sa fetoheng hore e be lintho tse hlahlobjoang habonolo.

MSTFA e ka sebelisoa bakeng sa ho ntša lipids, metsoako ea bioactive (joalo ka li-ketone le amino acid), le metsoako e nang le li-hydrogens tse sebetsang (tse kang aldehydes, ketones, le acid).

Mokhoa o tloaelehileng oa ho lokisa MSTFA ke ho arabela 2-methylsulfonyl-4-trifluoromethylphenylcarboxylic acid (MSTAA) ka fluorinated sulfoxide (SO2F2) kapa DAST (difluorothioamide trifluoromethanesulfonyl chloride).

Lintlha tsa polokeho ea MSTFA: E ka hlahisa likhase tse chefo kapa lintho tse senyang, 'me mehato e latelang ea polokeho e lokela ho lateloa:

Qoba ho ama letlalo, mahlo, kapa tsela ea ho hema, 'me u apare lisebelisoa tse loketseng tsa ho itšireletsa tse kang liatlana, likhalase le lisebelisoa tsa ho hema ha u sebelisa.

Sebetsa sebakeng se nang le moea o motle 'me u qobe ho hema mouoane kapa lerole la eona.

Ha u boloka, qoba mehloli ea mollo le lintho tse sa lumellaneng.

Ho lahloa ha litšila ho lokela ho tsamaellana le melao ea lehae 'me ha hoa lokela ho lahleloa ntle ho khethollo.
