Daim ntawv thov
1. Monoethyl fumarate yog fumaric acid ester siv nyob rau hauv dermatology; Kev sib xyaw ntawm Monoethyl fumarate ntsev (nrog dimethyl fumarate) tau pom zoo nyob rau hauv lub teb chaws Yelemees rau kev kho mob nruab nrab - rau - mob hnyav plaque psoriasis .
2. MEF CAS 2459-05-4 ua haujlwm ua haujlwm monomer hauv kev sib xyaw molecularly imprinted polymers (MIPs) rau kev xaiv kev sib cais ntawm alkaloids xws li scopolamine los ntawm cov khoom-theem extraction .
3. Monoethyl fumarate yog siv los ua cov tshuaj tua kab mob thiab cov khoom siv polymerization hauv siab - cov ntaub ntawv molecular , thiab ua cov cuab yeej tshawb fawb rau kev kawm txog kev ntxhov siab ntawm tes (NRF2 activation).
Cia thiab ceev faj
1. Khaws Monoethyl fumarate rau hauv ib lub thawv kaw nruj nreem rau hauv qhov chaw txias, qhuav. Rau ntev -lub sij hawm ruaj khov, khaws cov hmoov ntawm -20℃(txog 3 xyoos) lossis 4℃(txog 2 xyoos); Kev daws yuav tsum tau khaws cia ntawm -80 degree.
2. Khaws MEF CAS 2459-05-4 kom deb ntawm cov oxidizing muaj zog thiab cov hauv paus muaj zog.
3. Kov Monoethyl fumarate siv cov cuab yeej tiv thaiv tus kheej tsim nyog, vim Monoethyl fumarate tuaj yeem ua rau tawv nqaij, qhov muag, thiab ua pa ua pa (H315, H319, H335).
Kev kub ceev teb rau cov dej xau
1. Tshem tawm ntawm MEF CAS 2459-05-4 qhov chaw nchuav thiab hnav cov khoom tiv thaiv tus kheej, suav nrog cov tsom iav thiab hnab looj tes tiv thaiv.
2. cheb cov khoom Monoethyl fumarate thiab muab tso rau hauv ib lub thawv ntim khoom ntim rau pov tseg; nqus cov kev daws teeb meem nrog cov khoom siv inert (xws li diatomite) thiab decontaminate nto nrog cawv.
3. Tiv thaiv Monoethyl fumarate los ntawm kev nkag mus rau hauv qhov dej los yog hauv dej, thiab pov tseg tag nrho cov khoom pov tseg raws li cov cai hauv cheeb tsam.
Cov ntaub ntawv kev nyab xeeb
1. Monoethyl fumarate yog cais nrog GHS teeb liab lo lus "Ceeb toom" thiab ua rau tawv nqaij khaus (H315), mob qhov muag loj (H319), thiab tej zaum yuav ua rau ua pa ua pa (H335).
2. MEF CAS 2459-05-4 tej zaum yuav muaj teeb meem yog tias nqos tau (H302); Cov khoom toxicological ntawm Monoethyl fumarate tsis tau tshawb xyuas tag nrho, thiab nws yuav tsum tau ua raws li qhov nruab nrab mus rau qhov hnyav heev.
3. Nyob rau hauv hluav taws kub, thermal decomposition ntawm Monoethyl fumarate tej zaum yuav tsim cov pa phem xws li carbon monoxide, carbon dioxide, thiab nitrogen oxides.
