Daim ntawv thov
1. 5-Bromouracil yog ib qho halogenated pyrimidine analog siv los ua thymine antimetabolite hauv kev tshawb fawb biochemical thiab noob caj noob ces, qhov uas nws induces puag hloov pauv los ntawm kev koom ua ke rau hauv DNA nyob rau hauv qhov chaw ntawm thymine thiab mispairing nrog guanine .
2. 5-Bromouracil CAS 51-20-7 ua haujlwm raws li mutagen thiab ntom daim ntawv lo rau nucleic acids hauv kev tshawb fawb ntawm DNA replication, kho, thiab recombination, thiab yog dav siv nyob rau hauv kev soj ntsuam ntawm chromosome qauv thiab muaj nuj nqi.
3. 5-Bromouracil yog siv los ua cov tshuaj nruab nrab hauv kev sib txuas ntawm cov tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj tua kab mob, thiab tau kawm txog nws cov peev xwm hauv kev kho mob qog noj ntshav (PDT).
4. Cov kws tshawb nrhiav ntiav 5-Bromouracil CAS 51-20-7 hauv cell biology rau BrdU (5-bromo-2'-deoxyuridine) daim ntawv lo txhawm rau txhawm rau kuaj cov hlwb proliferating thiab txheeb xyuas cov cell voj voog kinetics hauv cov ntaub so ntswg.
Cia thiab ceev faj
1. 5-Bromouracil yuav tsum tau muab cia rau hauv lub thawv kaw nruj nreem nyob rau hauv qhov chaw txias, qhuav, thiab zoo - qhov cua nyob ib puag ncig ntawm 2-8℃(tub yees), tiv thaiv lub teeb thiab noo noo.
2. Rau ntev -lub sij hawm stability, cia ntawm -20℃yog pom zoo; cov kev daws teeb meem yuav tsum tau khaws cia ntawm -20℃txog li 1 lub hlis, tsis txhob rov qab khov-thaw mus.
3. 5-Bromouracil CAS 51-20-7 yog cais nrog GHS cov nqe lus txaus ntshai H315 (Ua rau tawv nqaij khaus), H319 (Ua rau qhov muag khaus hnyav), H335 (Tej zaum ua rau ua pa ua pa), H302 (teeb meem yog tias nqos), thiab H312 (tua phom sij rau hauv lo lus "Warning."
4. Cov neeg ua haujlwm yuav tsum hnav cov tshuaj lom neeg- cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb nrog sab - cov ntaub thaiv npog, thiab cov khaub ncaws tiv thaiv thaum tuav cov khoom no, ua kom muaj cua txaus hauv chaw ua haujlwm thiab zam kev tsim cov plua plav thiab aerosols.
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm qhov chaw nchuav, xyuas kom muaj qhov cua txaus, thiab hnav cov khoom tiv thaiv tus kheej nrog rau cov tshuaj lom neeg - cov hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab ua pa uas tsim nyog thaum 5-Bromouracil raug tso tawm.
2. Sau 5-Bromouracil CAS 51-20-7 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav siv cov cuab yeej tsis ua kom tawg, thiab muab tso rau hauv cov thawv kaw tsim nyog rau kev pov tseg.
3. Tsis txhob tsim cov huab cua thaum lub sij hawm ntxuav kom tsis txhob ua pa; tiv thaiv cov khoom los ntawm kev nkag mus rau hauv cov dej ntws los yog cov chav dej.
4. Pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig los ntawm kev tso cai los ntawm kev puas tsuaj los yog kev tswj incineration.
Kev tiv thaiv hluav taws
1. 5-Bromouracil tsis raug cais raws li cov nplaim hluav taws kub heev tab sis tuaj yeem tawg tau nyob rau hauv qhov hluav taws kub, emitting fumes xws li carbon monoxide, carbon dioxide, nitrogen oxides (NOx), thiab hydrogen bromide .
2. Siv cov tshuaj tsuag dej, tshuaj qhuav hmoov, carbon dioxide, los yog cawv- ua npuas ncauj resistant los tua hluav taws nrog cov khoom; Tsis txhob siv lub dav hlau dej ncaj qha raws li 5-Bromouracil CAS 51-20-7 tuaj yeem tawg cov khoom tawg.
3. Cov neeg tua hluav taws yuav tsum hnav tus kheej- muaj cov cuab yeej ua pa hauv siab- thov, MSHA/NIOSH tau pom zoo, thiab cov iav tiv thaiv tag nrho thaum tuav cov hluav taws kub 5-Bromouracil vim muaj cov pa phem uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; muaj hluav taws kub los tiv thaiv ib puag ncig.
