I-2-Methylsulfonyl-4-trifluoromethylbenzoic Acid (CAS # 142994-06-7) isingeniso

I-2-methylsulfonyl-4-trifluoromethylbenzoic acid (MSTFA) yi-organic compound eneempawu ezilandelayo:

Imbonakalo: I-MSTFA lulwelo olungenambala ukuya kumthubi okhanyayo.

Ukunyibilika: Kunyibilika kwiintlobo ezininzi ze-organic solvents, ezifana ne-dimethylformamide, i-acetonitrile, kunye ne-methanol.

Uzinzo: I-MSTFA yikhompawundi ezinzile, kodwa inokubola kwaye ivelise iigesi eziyityhefu okanye izinto ezidliwayo ngexesha lokugcina okanye lokufudumeza.

I-MSTFA isetyenziselwa ikakhulu ukuhlalutya ukuvela kwezinto kwikhemistri, kunye nezicelo ezithile ezibandakanya:

Kuhlalutyo lwegesi yechromatography-mass spectrometry (GC-MS), i-MSTFA isetyenziswa njenge-reagent ephuma kwisampulu yonyango lwangaphambili, enokuguqula iikhompawundi ezingaguquguqukiyo zibe ziziphuma ngokulula ezinokucazululeka.

I-MSTFA ingasetyenziselwa ukukhupha i-lipids, izinto ezisebenzayo (ezifana neeketones kunye ne-amino acids), kunye neekhompawundi ezine-hydrogens ezisebenzayo (ezifana ne-aldehydes, i-ketones, kunye ne-acids).

Indlela eqhelekileyo yokulungiselela i-MSTFA kukusabela i-2-methylsulfonyl-4-trifluoromethylphenylcarboxylic acid (MSTAA) kunye ne-fluorinated sulfoxide (SO2F2) okanye i-DAST (difluorothioamide trifluoromethanesulfonyl chloride).

Ulwazi ngokhuseleko lwe-MSTFA: Inokuvelisa iigesi eziyityhefu okanye izinto ezidlayo, kwaye la manyathelo okhuseleko alandelayo kufuneka alandelwe:

Kuphephe ukudibana nolusu, amehlo, okanye umjelo wokuphefumla, kwaye unxibe izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, iiglasi, kunye neziphefumlo xa usebenzisa.

Sebenza kwindawo engena umoya kwaye uphephe ukuphefumla umphunga okanye uthuli.

Xa ugcina, zigcine kude nemithombo yomlilo nezinto ezingahambelaniyo.

Ukulahlwa kwenkunkuma kufuneka kuhambelane nemigaqo yasekuhlaleni kwaye akufuneki ilahlwe ngokungenamkhethe.
