Daim ntawv thov
1. tert-Butyl bromoacetate yog dav siv los ua tus neeg sawv cev alkylating thiab tseem ceeb nruab nrab ntawm cov organic synthesis rau kev tsim tshuaj, agrochemicals, dyes, thiab ntau yam organic compounds. Tert-Butyl bromoacetate CAS 5292-43-3 plays lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm collagenase inhibitors thiab (2-}oxo-4-vinyl-azetidin-1-yl)-acetic acid tert-butyl ester .
2. Lub compound ua hauj lwm pab raws li ib tug ntau yam tsev thaiv nyob rau hauv tshuaj chemistry, siv nyob rau hauv lub synthesis ntawm aldose reductase inhibitors rau kev tshawb fawb ntshav qab zib, bifunctional chelating agents rau radiopharmaceuticals, thiab pseudodipeptide tsev blocks rau peptide tshuaj hloov kho.
3. Cov ntawv thov ntawm tert-Butyl bromoacetate kuj suav nrog nws siv hauv polymer chemistry rau synthesizing functionalized polymers thiab ua ib qho pib reagent rau N- hloov oligoglycines (peptoids) thiab N-Oxalylglycine derivatives .
Cia thiab ceev faj
1. Khaws tert-Butyl bromoacetate nyob rau hauv ib lub thawv kaw nruj nreem nyob rau hauv ib tug inert gas (xws li, nitrogen los yog argon) nyob rau hauv ib tug txias, qhuav, thiab zoo- qhov chaw cua. Pom zoo cia kub sib txawv ntawm lub tub yees (2-8 degree) mus rau qhov chaw txias, tsaus nti hauv qab 15 degree, vim nws yog hygroscopic thiab decomposes hauv huab cua noo.
2. Khaws tert-Butyl bromoacetate nruj me ntsis kom deb ntawm cov oxidizing muaj zog thiab cov hauv paus muaj zog vim tsis sib haum. Tiv thaiv los ntawm tshav kub, sparks, thiab qhib nplaim taws raws li nws yog ib tug flammable kua nrog ib tug flash point ntawm 49℃(120℃F).
3. Ib txwm Tert-Butyl bromoacetate CAS 5292-43-3 siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) suav nrog tshuaj lom neeg- hnab looj tes tiv thaiv (butyl-rubber lossis nitrile pom zoo), nruj nruj tsom iav tsom iav, ntaub thaiv npog ntsej muag, thiab khaub ncaws tiv thaiv. Tuav tsuas yog nyob rau hauv cov tshuaj fume hood nrog cov khoom tawg-pov thawj kom tsis txhob ua pa vapors thiab tiv thaiv daim tawv nqaij / qhov muag.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais qhov chaw nchuav, tshem tawm tag nrho cov qhov hluav taws xob, thiab muab qhov cua txaus. Muaj tert-Butyl bromoacetate siv inert, tsis yog- cov khoom siv hluav taws xob uas muaj hluav taws xob (xws li cov xuab zeb qhuav, universal binder) thiab tiv thaiv kev nkag mus rau hauv cov dej ntws los yog cov dej ntws.
2. Ua tib zoo sau Tert-Butyl bromoacetate CAS 5292-43-3 siv tsis yog- cov cuab yeej hluav taws xob lossis lub tshuab nqus hluav taws xob tawg rau hauv lub kaw lus, sau ntawv, tshuaj tiv thaiv corrosion-resistant rau pov tseg raws li hauv zos, xeev, thiab tsoom fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg tag nrho - cov cuab yeej tiv thaiv nrog rau tus kheej -cov cuab yeej ua pa (SCBA) thaum ntxuav. tert-Butyl bromoacetate yog cais rau kev thauj mus los (UN2924 lossis UN1993, Hazard Class 3/8, PG III).
Cov ntaub ntawv kev nyab xeeb
1. tert-Butyl bromoacetate yog cais ua kua thiab vapor (H226) thiab yog corrosive, ua rau tawv nqaij kub hnyiab thiab mob qhov muag (H314/H318). Tert-Butyl bromoacetate CAS 5292-43-3 muaj teeb meem yog tias nqos tau (H302) nrog qhov ncauj LD50 ntawm 400 mg / kg hauv nas, thiab tej zaum yuav ua rau ua pa ua pa (H335).
2. tert-Butyl bromoacetate reacts nrog dej thiab yog incompatible nrog muaj zog oxidizing agents thiab bases. Vapors hnyav dua li huab cua thiab tuaj yeem tsim cov khoom tawg. Thermal decomposition ua rau cov pa phem thiab corrosive xws li carbon monoxide, carbon dioxide, thiab hydrogen bromide gas. GHS teeb liab lo lus yog "Danger".
3. Nco ntsoov sab laj rau Daim Ntawv Qhia Txog Kev Nyab Xeeb Tshwj Xeeb (SDS) rau tert-Butyl bromoacetate kom tiav cov ntaub ntawv txaus ntshai, ua ntej- txheej txheem pab (P303+P361+P353 rau daim tawv nqaij, P305+P351+P338 rau ob lub qhov muag, P- cov lus qhia rau tes, P{310}Pest Cov lus ceeb toom muaj xws li P210 (kom deb ntawm tshav kub / taws / qhib nplaim taws), P233 (kom kaw lub thawv kom nruj), thiab P280 (hnav looj hnab looj tes / tiv thaiv qhov muag).
