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

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

2-methylsulfonyl-4-trifluoromethylbenzoic acid (MSTFA) waa unug dabiici ah oo leh sifooyinka soo socda:

Muuqashada: MSTFA waa dareere huruud ah oo aan midab lahayn ama iftiin leh.

Solubility: Waxay ku milmi kartaa inta badan dareerayaasha organic, sida dimethylformamide, acetonitrile, iyo methanol.

Xasilooni: MSTFA waa iskudhis xoogaa xasiloon, laakiin waxa laga yaabaa inay qudhunto oo ay soo saarto gaasas sun ah ama walxo daxal ah inta lagu jiro kaydinta ama kuleylka.

MSTFA waxaa inta badan loo isticmaalaa in lagu falanqeeyo falcelinta kala soocida ee kimistariga, oo leh codsiyo gaar ah oo ay ka mid yihiin:

Falanqaynta gaaska-chromatography-mass spectrometry (GC-MS), MSTFA waxa loo istcimaalay sidii reagent derivative for pretreatment muunad, kaas oo u rogi kara xeryahooda aan isbedbeddelayn si fududna loo falanqeyn karo.

MSTFA waxaa loo isticmaali karaa soo saarista xuubka, walxaha bioactive (sida ketones iyo amino acids), iyo xeryahooda leh hydrogens firfircoon (sida aldehyde, ketones, iyo acids).

Habka caadiga ah ee diyaarinta MSTFA waa ka falcelinta 2-methylsulfonyl-4-trifluoromethylphenylcarboxylic acid (MSTAA) leh sulfoxide fluorinated (SO2F2) ama DAST (difluorothioamide trifluoromethanesulfonyl chloride).

Macluumaadka badbaadada MSTFA: Waxa laga yaabaa inay soo saarto gaas sun ah ama walxo wasakh ah, waana in la raaco tillaabooyinka badbaadada ee soo socda:

Ka fogow taabashada maqaarka, indhaha, ama mareenka neefsiga, oo xidho qalabka ilaalinta ku habboon sida galoofyada, muraayadaha, iyo qalabka neefsashada markaad isticmaalayso.

Ka shaqee meel hawo fiican leh oo iska ilaali in aad neefsato uumiga iyo siigada.

Markaad kaydinayso, ka fogow ilaha dabka iyo alaabta aan isqaban karin.

Qashin tuurista waa in ay u hoggaansamaan xeerarka deegaanka waana in aan si aan kala sooc lahayn loo daadin.
