Daim ntawv thov
1. 4-Nitrophenyl chloroformate feem ntau yog siv los ua cov tshuaj chloroformate reagent rau kev qhia 4-nitrophenyloxycarbonyl (PNP) tiv thaiv pab pawg lossis ua kom muaj carboxylic acids thiab cawv hauv peptide synthesis thiab bioconjugation.
2. 4-Nitrophenyl chloroformate CAS 7693-46-1 yog ib qho tseem ceeb nruab nrab rau kev sib xyaw carbonates, carbamates, thiab lwm yam kev ua haujlwm ntawm cov organic tebchaw hauv kev tshawb fawb tshuaj thiab agrochemical.
3. Cov tshuaj no kuj tseem siv tau rau hauv cov tshuaj polymer rau kev hloov kho saum npoo thiab ua tus ntoo khaub lig- txuas tus neeg sawv cev.
Cia thiab ceev faj
1. Khaws 4-nitrophenyl chloroformate nyob rau hauv ib qho chaw inert (xws li, nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, zoo-ventilated qhov chaw, deb ntawm noo noo, tshav kub, thiab incompatible ntaub ntawv.
2. Khaws 4-Nitrophenyl chloroformate CAS 7693-46-1 lub thawv kaw kom nruj thiab muaj cov ntawv sau meej meej. Khaws cais tawm ntawm dej, cawv, amines, bases, thiab oxidizing agents.
3. Ua tib zoo ceev faj siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE): tshuaj lom neeg -cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, daim npog ntsej muag, thiab cov kua qaub- cov tshuaj tiv thaiv lab lub tsho. Txhua zaus siv lub fume hood.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm tam sim ntawd thiab cais thaj chaw. Xyuas kom qhov cua thiab hnav cov iav tiv thaiv tag nrho (cov hnab looj tes, tsom iav, khaub ncaws tiv thaiv, lub tshuab ua pa haum rau cov kua qaub vapors / chlorides).
2. **Tsis txhob siv cov dej los yog cov ntaub ntub dej.** Ua tib zoo npog cov nchuav nrog cov dej tsis zoo, qhuav nqus (xws li xuab zeb, vermiculite). Muab tag nrho cov khoom tsis huv tso rau hauv ib lub thawv ntim khoom kaw, sau tias muaj kev phom sij.
3. Tiv thaiv 4-Nitrophenyl chloroformate CAS 7693-46-1 los ntawm kev nkag mus rau hauv cov kav dej, cov kav dej, lossis ib puag ncig. Decontaminate cov cuab yeej thiab qhov chaw nrog cov khoom qhuav inert ua ntej. Nrhiav kev pab kws kho mob.
Cov ntaub ntawv kev nyab xeeb
1. 4-Nitrophenyl chloroformate yog ** corrosive heev, noo noo-sensitive, thiab toxic **. Nws ua rau tawv nqaij kub hnyiab, qhov muag puas, thiab ua pa puas. Nws reacts hnyav nrog dej, cawv, thiab hauv paus, tso cua sov thiab tshuaj lom / corrosive gases (hydrogen chloride, phosgene, 4-nitrophenol).
2. 4-Nitrophenyl chloroformate CAS 7693-46-1 yog combustible thiab tej zaum yuav emit cov pa phem heev (hydrogen chloride, phosgene, nitrogen oxides, carbon monoxide) thaum tshav kub los yog nyob rau hauv hluav taws.
3. **Nco ntsoov sab laj nrog 4-nitrophenyl chloroformate Safety Data Sheet (SDS) thiab ua raws li kev noj qab haus huv, corrosion, thiab reactivity txaus ntshai.** Kev cob qhia tshwj xeeb rau chloroformates yog yuav tsum tau.
