Trometamol (Tris (Hydroxymethyl) aminomethane (Trometamol) siab purity)
| Tshuaj lom neeg | Dawb siv lead ua los yog hmoov.Soluble nyob rau hauv ethanol thiab dej, me ntsis soluble nyob rau hauv ethyl acetate, benzene, insoluble nyob rau hauv ether, carbon tetrachloride, tooj liab, txhuas corrosion teebmeem, irritant. | |
| Daim ntawv thov | Tris, los yog tris (hydroxymethyl) aminomethane, los yog paub thaum siv kho mob raws li tromethamine los yog THAM, yog cov organic compound nrog cov mis (HOCH2) 3CNH2.Nws yog dav siv hauv biochemistry thiab molecular biology ua ib feem ntawm cov kev daws teeb meem tsis xws li hauv TAE thiab TBE buffers, tshwj xeeb tshaj yog rau cov kev daws teeb meem ntawm nucleic acids.Nws muaj ib tug thawj amine thiab yog li undergoes cov kev cuam tshuam nrog ib txwm amines, xws li condensations nrog aldehydes.Tris kuj complexes nrog hlau ions hauv kev daws.Hauv cov tshuaj, tromethamine yog qee zaus siv los ua tshuaj, muab kev saib xyuas hnyav rau nws cov khoom raws li qhov tsis zoo rau kev kho mob hnyav metabolic acidosis hauv qee qhov xwm txheej.Qee cov tshuaj tau tsim ua "tromethamine ntsev" suav nrog hemabate (carboprost li trometamol ntsev), thiab "ketorolac trometamol". | |
