Cov ntawv thov ntawm Methoxyacetic anhydride kuj suav nrog nws siv hauv esterification thiab acylation cov tshuaj tiv thaiv raws li tus neeg pub dawb acyl, qhov twg nws cov metabolite methoxyacetic acid tau kawm rau histone deacetylase (HDAC) inhibition hauv kev mob qog noj ntshav thiab teratogenicity tshawb fawb.
Cia thiab ceev faj
1. Khaws Methoxyacetic anhydride nyob rau hauv lub thawv kaw nruj nreem nyob rau hauv inert gas (xws li, nitrogen) nyob rau hauv ib tug txias, qhuav qhov chaw, zoo tagnrho ntawm -20℃los yog refrigerated (2-8 degree), thiab nruj me ntsis tiv thaiv los ntawm noo noo.
2. Khaws Methoxyacetic anhydride kom deb ntawm cov muaj zog oxidizing cov neeg ua haujlwm, cov hauv paus, thiab txo cov neeg ua haujlwm vim tsis sib haum xeeb thiab muaj peev xwm ua rau muaj kev kub ntxhov; zam kom raug lub teeb kom ntev - lub sij hawm ncaj ncees .
3. Ib txwm siv Methoxyacetic anhydride CAS 19500-95-9 cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE) nrog rau cov hnab looj tes tiv thaiv tshuaj, tsom iav tiv thaiv, thiab khaub ncaws tiv thaiv thaum tuav Methoxyacetic anhydride kom tsis txhob muaj kev sib cuag nrog cov dej noo-rhiab thiab corrosive.
Kev kub ceev teb rau cov dej xau
1. Tam sim ntawd cais thaj chaw nchuav, xyuas kom muaj qhov cua txaus, thiab muaj Methoxyacetic anhydride siv inert, tsis yog -cov khoom siv hluav taws xob tsis zoo; tiv thaiv kev nkag mus rau hauv qhov dej los yog txoj kev dej.
2. Ua tib zoo sau Methoxyacetic anhydride CAS 19500-95-9 siv cov cuab yeej tsis cuam tshuam thiab muab tso rau hauv ib lub thawv ntim khoom uas muaj cov tshuaj tiv thaiv corrosion-resistant rau pov tseg raws li hauv zos, xeev, thiab tseem fwv cov kev cai ib puag ncig.
3. Cov neeg ua haujlwm yuav tsum hnav PPE tsim nyog suav nrog tshuaj lom neeg- khaub ncaws tiv thaiv tus kheej thiab tus kheej-cov cuab yeej ua pa (SCBA) thaum ntxuav; Methoxyacetic anhydride yog cais rau kev thauj mus los (UN3265, Hazard Class 8, PG III) ua kua corrosive.
Cov ntaub ntawv kev nyab xeeb
1. Methoxyacetic anhydride yog cais raws li cov khoom corrosive (GHS05, Danger) ua rau cov tawv nqaij kub hnyiab thiab qhov muag loj (H314/H318).
2. Methoxyacetic anhydride yog noo noo rhiab heev, soluble hauv dej (193 g / L ntawm 25 degree), thiab reacts nrog dej los tsim methoxyacetic acid; Nws cov thermal decomposition ua rau cov pa phem thiab khaus khaus xws li carbon oxides.
3. Nco ntsoov sab laj Methoxyacetic anhydride CAS 19500-95-9 daim ntawv Qhia Kev Nyab Xeeb tshwj xeeb (SDS) rau Methoxyacetic anhydride kom tiav cov ntaub ntawv txaus ntshai, cov txheej txheem pab thawj zaug (P305+P351+P338 rau qhov muag, P301+P330+P31, P303+P361+P353 rau daim tawv nqaij), thiab cov lus qhia tuav; Cov lus ceeb toom muaj xws li P260 (tsis txhob ua pa vapors), P280 (hnav looj hnab looj tes tiv thaiv qhov muag), thiab P405 (khoom kaw cia).
