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

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

2-methylsulfonyl-4-trifluoromethylbenzoic acid (MSTFA) ndi organic pawiri yokhala ndi zotsatirazi:

Maonekedwe: MSTFA ndi madzi achikasu opepuka opanda mtundu.

Kusungunuka: Amasungunuka mu zosungunulira zambiri za organic, monga dimethylformamide, acetonitrile, ndi methanol.

Kukhazikika: MSTFA ndi gulu lokhazikika, koma limatha kuwola ndikutulutsa mpweya wapoizoni kapena zinthu zowononga posungira kapena kutentha.

MSTFA imagwiritsidwa ntchito makamaka pakuwunika momwe zimakhalira mu chemistry, ndikugwiritsa ntchito mwapadera kuphatikiza:

Pakuwunika kwa gasi chromatography-mass spectrometry (GC-MS), MSTFA imagwiritsidwa ntchito ngati chinthu chochokera pazitsanzo za pretreatment, zomwe zimatha kusintha zinthu zosasunthika kukhala zotuluka mosavuta.

MSTFA ingagwiritsidwe ntchito potulutsa lipids, bioactive zinthu (monga ketoni ndi amino zidulo), ndi mankhwala ndi haidrojeni yogwira (monga aldehydes, ketoni, ndi zidulo).

Njira yodziwika bwino yokonzekera MSTFA ndikuchita 2-methylsulfonyl-4-trifluoromethylphenylcarboxylic acid (MSTAA) ndi fluorinated sulfoxide (SO2F2) kapena DAST (difluorothioamide trifluoromethanesulfonyl chloride).

Chidziwitso chachitetezo cha MSTFA: Itha kutulutsa mpweya wapoizoni kapena zinthu zowononga, ndipo izi ziyenera kutsatiridwa:

Pewani kukhudza khungu, maso, kapena kupuma, ndipo valani zida zodzitetezera zoyenera monga magolovesi, magalasi, ndi zopumira mukamagwiritsa ntchito.

Gwirani ntchito pamalo olowera mpweya wabwino ndipo pewani kutulutsa nthunzi kapena fumbi lake.

Posunga, khalani kutali ndi magwero a moto ndi zinthu zosagwirizana.

Kutaya zinyalala kuyenera kutsatira malamulo a m’deralo ndipo sikuyenera kutayidwa mwachisawawa.
