DL-Valine CAS 516-06-3

1. DL-Valine yog ib hom kev sib xyaw ntawm cov amino acid tseem ceeb valine, siv los ua lub tsev thaiv hauv kev tshawb fawb biochemical thiab ua tus thawj coj hauv peptide synthesis thiab organic chemistry.
2. DL-Valine CAS 516-06-3 ua haujlwm raws li cov txheej txheem substrate thiab analytical standard nyob rau hauv kev tshawb fawb ntawm amino acid metabolism, thauj mechanisms, thiab enzymatic cov tshuaj tiv thaiv.
3. DL-Valine yog ua haujlwm hauv kev tshawb fawb txog zaub mov thiab kev noj zaub mov ntxiv raws li qhov chaw valine rau ob qho tib si L- thiab D- isomers .
4. Cov kws tshawb fawb siv cov khoom no rau R & D lub hom phiaj nkaus xwb, qhov twg nws cov stereochemistry sib npaug ua rau nws muaj txiaj ntsig rau kev kawm racemic sib xyaw hauv ntau lub tshuab lom neeg thiab tshuaj lom neeg.

1. DL-Valine yuav tsum muab khaws cia rau hauv lub thawv kaw nruj nreem rau hauv qhov chaw txias, qhuav, thiab zoo- qhov cua; pom zoo cia nyob rau hauv chav tsev kub (RT) nyob rau hauv ib tug txias, tsaus qhov chaw los yog ntawm -20℃rau lub sij hawm ntev stability.
2. DL-Valine CAS 516-06-3 feem ntau tsis raug cais raws li cov khoom siv phom sij raws li GHS cov qauv, txawm hais tias qee qhov chaw qhia tias muaj kev phom sij H315 (ua rau tawv nqaij khaus), H319 (Ua rau qhov muag khaus), thiab H335 (Tej zaum ua rau ua pa ua pa).
3. 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, zam kev tsim cov plua plav thiab aerosols.
4. Khaws kom deb ntawm cov khoom siv tsis sib xws xws li muaj zog oxidizing tus neeg sawv cev; rau cov tshuaj cia, npaj aliquots nyob rau hauv nruj nreem kaw vials thiab siv nyob rau hauv lub sij hawm pom zoo, tsis txhob rov qab khov -thaw cycles .

1. Tshem tawm ntawm qhov chaw nchuav, ua kom muaj cua txaus, thiab hnav cov khoom tiv thaiv tus kheej tag nrho nrog rau cov tshuaj lom neeg - hnab looj tes tiv thaiv, tsom iav kev nyab xeeb, thiab lub tshuab nqus plua plav tsim nyog thaum DL-Valine tawm.
2. Sau DL-Valine CAS 516-06-3 los ntawm kev cheb lossis nqus tsev yam tsis tsim cov plua plav uas 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; Tsis muaj kev ceev faj tshwj xeeb ib puag ncig, tab sis kev tawm mus rau hauv cov dej yuav tsum tau tiv thaiv.
4. Muab pov tseg cov ntaub ntawv khaws tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig, muab cov khoom seem thiab tsis yog - rov ua dua tshiab rau lub tuam txhab pov tseg uas muaj ntawv tso cai.

1. DL-Valine tsis raug cais raws li cov nplaim taws heev nrog NFPA qhov ntsuas hluav taws kub ntawm 1 (cov khoom siv uas yuav tsum tau ua kom muaj cua sov ntau ua ntej ignition); Nyob rau hauv cov xwm txheej hluav taws kub, cov khoom puas tsuaj muaj xws li cov pa roj carbon monoxide, carbon dioxide, thiab nitrogen oxides (NOx).
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 DL-Valine CAS 516-06-3 tuaj yeem tawg cov khoom siv hluav taws xob.
3. Cov neeg tua hluav taws yuav tsum hnav nws 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 kub hnyiab DL-Valine vim muaj kev puas tsuaj rau cov pa roj uas tsim los ntawm thermal decomposition .
4. Thaum lub sij hawm combustion, tej zaum yuav emit irritant thiab toxic fumes; txav cov thawv los ntawm qhov chaw tua hluav taws yog tias muaj kev nyab xeeb ua li ntawd, thiab muaj cov hluav taws kub los tiv thaiv ib puag ncig.
