Dulmar:Magaca calaamada Tris waa tris (hydroxymethyl) aminomethane;trometamine;trometamine;2-amino-2-(hydroxymethyl) -1,3-propanediol.Waa crystal cad ama budo.Ku milmay ethanol iyo biyaha, wax yar ku milma ethyl acetate iyo benzene, aan milmin ether iyo carbon tetrachloride, daxalaysa naxaas iyo aluminium, iyo kiimikooyin xajiimo leh.
Tilmaamaha:Tromethamine waa saldhigga amino-ka-soo-baxa-free, kaas oo la falgala H2CO3 ee dareeraha jidhka si loo yareeyo H2CO3 oo ay dhaliso HCO32- isku mar.Waxay nuugi kartaa ions hydrogen waxayna hagaajin kartaa aashitada.Xoog badan, oo geli kara xuubka unugyada, oo caadi ahaan loo isticmaalo dheef-shiid kiimikaad ba'an iyo aashitada neefsiga.
Guryaha kaydinta:Tris waa saldhig daciif ah oo leh pKa 8.1 at 25 ° C;marka loo eego aragtida kaydinta, kala duwanaanshaha wax-ku-oolka ah ee kaydinta Tris waa inta u dhaxaysa pH 7.0 iyo 9.2.pH ee xalka aqueous ee saldhiga Tris waa qiyaastii 10.5.Guud ahaan, hydrochloric acid ayaa lagu daraa si loo hagaajiyo qiimaha pH ee qiimaha la rabo, ka dibna xalka kaydinta leh qiimaha pH waa la heli karaa.Si kastaba ha ahaatee, waa in fiiro gaar ah loo yeesho saameynta heerkulka pKa of Tris.
Codsiga:Tris waxaa si weyn loogu isticmaalaa dheef-shiid kiimikaad ba'an iyo aashitada neefsiga.Waa kaydka alkaline waxayna saameyn wanaagsan ku leedahay aashitada dheef-shiid kiimikaadka iyo dhaqdhaqaaqa enzymatic.Tris waxaa inta badan loo isticmaalaa sidii bayooloji oo badiyaa lagu qaabeeyey qiimaha pH ee 6.8, 7.4, 8.0, iyo 8.8.Qaab dhismeedkeeda iyo qiimaha pH aad bay ugu kala duwan yihiin heerkulka.Guud ahaan Buuga Kiimikada ayaa sheegaya in darajo kasta oo kororka heerkulka, pH ay hoos u dhacdo 0.03.Tris waxaa si weyn loogu isticmaalaa diyaarinta kaydka ee tijaabooyinka bayoolojiga iyo molecular.Tusaale ahaan, Tris ayaa looga baahan yahay labadaba TAE iyo TBE baffers (oo loogu talagalay solubilization of nucleic acids) oo caadi ahaan loo isticmaalo tijaabooyinka kiimikaad.Maadaama ay ka kooban tahay kooxda amino, waxay la kulmi kartaa falcelinta uumiga aldehyde.
