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

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

2-methylsulfonyl-4-trifluoromethylbenzoic acid (MSTFA) wani fili ne na kwayoyin halitta tare da kaddarorin masu zuwa:

Bayyanar: MSTFA ruwa ne mara launi zuwa haske.

Solubility: Yana da narkewa a cikin mafi yawan kaushi na halitta, kamar dimethylformamide, acetonitrile, da methanol.

Kwanciyar hankali: MSTFA wani fili ne mai inganci, amma yana iya rubewa ya haifar da iskar gas mai guba ko abubuwa masu lalata yayin ajiya ko dumama.

Ana amfani da MSTFA musamman don nazarin halayen haɓakawa a cikin sinadarai, tare da takamaiman aikace-aikacen da suka haɗa da:

A cikin bincike na chromatography-mass spectrometry (GC-MS), MSTFA ana amfani dashi azaman reagent na asali don samfurin pretreatment, wanda zai iya canza mahaɗan da ba sa canzawa zuwa abubuwan da ake iya tantancewa cikin sauƙi.

Ana iya amfani da MSTFA don rarrabuwar lipids, abubuwa masu rai (kamar ketones da amino acid), da mahadi tare da hydrogens masu aiki (kamar aldehydes, ketones, da acids).

Hanyar gama gari don shirya MSTFA shine amsa 2-methylsulfonyl-4-trifluoromethylphenylcarboxylic acid (MSTAA) tare da sulfoxide fluorinated (SO2F2) ko DAST (difluorothioamide trifluoromethanesulfonyl chloride).

Bayanin aminci na MSTFA: Yana iya haifar da iskar gas mai guba ko abubuwa masu lalata, kuma yakamata a bi matakan tsaro masu zuwa:

Guji cudanya da fata, idanu, ko hanyoyin numfashi, kuma sanya kayan kariya masu dacewa kamar safar hannu, tabarau, da na'urar numfashi yayin amfani da su.

Yi aiki a cikin wurin da ke da iska sosai kuma ka guji shakar tururinsa ko ƙura.

Lokacin adanawa, nisanta daga tushen wuta da kayan da ba su dace ba.

Ya kamata zubar da shara ya bi ka'idodin gida kuma kada a zubar da shi ba gaira ba dalili.
