2. Khaws Pentafluorophenol CAS 771-61-9 kom deb ntawm tshav kub, qhib nplaim taws thiab oxidants; zam kev sib cuag nrog cov hauv paus muaj zog thiab cov kua qaub kom tsis txhob decomposition.
3. Hnav hnab looj tes nitrile, tsom iav tiv thaiv tshuaj lom neeg thiab lub tshuab nqus plua plav/vapor respirator thaum tuav cov khoom crystalline.
4. Tshem tawm Pentafluorophenol CAS 771-61-9 ntawm cov khoom pov tseg thiab cov khoom tsis huv los ntawm cov chaw muab kev pabcuam pov tseg pov tseg uas muaj ntawv tso cai.
Dab tsi yog qhov txiaj ntsig ntawm kev noj Pentafluorophenol?
1. Tsib fluorine hloov tau txhim khu lub electrophilicity ntawm active esters, txhawb siab -efficiency peptide coupling tshua.
2. Hydroxyl Pentafluorophenol CAS 771-61-9 pab pawg ua kom yooj yim tsim cov esters nquag, txhawb kev sib txawv amidation thiab esterification cov tshuaj tiv thaiv.
3. Muab pov thawj zoo solubility hauv cov kuab tshuaj organic xws li DMF thiab ethyl acetate, haum rau ntau yam tshuaj tiv thaiv kab mob.
4. Muaj Pentafluorophenol CAS 771-61-9 siab reactivity thiab stability, zoo tagnrho rau ob qho tib si kuaj-scale R&D thiab industrial-scale peptide thiab tshuaj ntau lawm.
Cov ntaub ntawv kev nyab xeeb
Cov tshuaj no raug cais raws li ua rau tawv nqaij kub hnyiab thiab qhov muag puas (H314), teeb meem yog nqos tau (H302), thiab khaus rau txoj hlab pa (H335). Pentafluorophenol CAS 771-61-9 yog incompatible nrog muaj zog bases, acids thiab oxidants; decomposition yuav tso tawm cov pa phem hydrogen fluoride. Cov khoom siv tuaj yeem ua rau tawv nqaij thiab qhov muag corrosion thaum sib cuag, thiab nqus tau cov plua plav lossis vapors tuaj yeem ua rau ua pa ua pa thiab puas. Nws tsis yog cov khoom tawg yooj yim, tab sis cua sov rau qhov kub siab tuaj yeem tsim cov khoom puas tsuaj.
