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

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

2-methylsulfonyl-4-trifluoromethylbenzoic acid (MSTFA) o se faʻalapotopotoga faʻapitoa ma mea nei:

Fa'aaliga: MSTFA ose vai e leai se lanu i se vai samasama.

Solubility: E solu i le tele o solvents organic, e pei o le dimethylformamide, acetonitrile, ma le methanol.

Mausalī: MSTFA ose fa'aputuga mautu, peita'i e mafai ona pala ma maua mai ai kasa o'ona po'o mea e pala a'o teuina pe fa'avevela.

O le MSTFA e masani ona faʻaaogaina mo le suʻesuʻeina o gaioiga faʻatupu i le kemisi, faʻatasi ai ma faʻaoga faʻapitoa e aofia ai:

I le kasa chromatography-mass spectrometry (GC-MS) su'esu'ega, o lo'o fa'aaogaina le MSTFA e fai ma fa'ata'ita'iga fa'ata'ita'iga mo le fa'ata'ita'iga muamua, lea e mafai ona fa'aliliuina fa'aputuga e le fa'afefeteina i mea e maua mai ai e faigofie ona su'esu'eina.

E mafai ona fa'aogaina le MSTFA mo le fa'atupuina o ga'o, mea fa'aolaola (e pei o ketones ma amino acids), ma fa'afefiloi ma hydrogens malosi (e pei o aldehydes, ketones, ma acids).

O se auala masani mo le sauniaina o le MSTFA o le tali atu lea i le 2-methylsulfonyl-4-trifluoromethylphenylcarboxylic acid (MSTAA) ma le sulfoxide fluorinated (SO2F2) poʻo le DAST (difluorothioamide trifluoromethanesulfonyl chloride).

Fa'amatalaga mo le saogalemu o le MSTFA: E ono maua mai ai kasa o'ona po'o mea e pala, ma e tatau ona mulimulita'i i faiga saogalemu nei:

Aloese mai le fa'afeso'ota'i ma le pa'u, mata, po'o le manava, ma fa'aaoga mea e puipuia ai e pei o totigilima, mata tioata, ma manava pe a fa'aaoga.

Fa'agaoioi i totonu o se nofoaga e fa'alelei lelei ma aloese mai le manavaina o ona ausa po'o le pefu.

Pe a teuina, ia taumamao mai puna o afi ma mea e le fetaui.

O le lafoaia o otaota e tatau ona tausisia tulafono a le lotoifale ma e le tatau ona lafoai fua.
