    Kugwiritsa ntchito

    1.Ndi chakudya chokoma, makamaka chomwe chimagwiritsidwa ntchito pokonzekera zokometsera za zipatso monga mapeyala, maapulo, mphesa ndi yamatcheri.

    2.Amagwiritsidwa ntchito kwambiri popanga barbituric acid, amino acid, Mavitamini B1, B2 ndi B6, mankhwala ogona ndi phenylbutazone.

    3.Amagwiritsidwanso ntchito kwambiri m'madera ena opanga mankhwala, kuphatikizapo mankhwala ophera tizilombo, utoto wa mafakitale, zipangizo zamadzimadzi za crystal, etc.

    Katundu

    Amasungunuka mu chloroform, benzene ndi ma organic solvents. Zosungunuka pang'ono m'madzi.

    Kusungirako

    1. Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino. Khalani kutali ndi gwero la moto ndi kutentha. Iyenera kusungidwa mosiyana ndi zowonjezera zowonjezera, ma alkali amphamvu, ndi othandizira kuchepetsa, ndipo pewani kusungirako kosakanikirana. Okonzeka ndi mitundu yoyenera komanso kuchuluka kwa zida zozimitsa moto. Malo osungiramo zinthu ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zosungirako.

    2. Sungani ndi kuyendetsa motsatira malamulo a mankhwala oyaka moto.

    Kukhazikika

    1. Pewani kukhudzana ndi okosijeni, zochepetsera ndi alkalis. Mankhwalawa amakhala okhazikika kuposa diethyl oxalate. Popeza mosavuta hydrolyzed kupanga malonic asidi, amene ali acidic kwambiri, m`pofunika kupewa inhalation wa nthunzi kapena kukhudzana ndi khungu.

    2. Izi mankhwala otsika kawopsedwe, makoswe pakamwa LD50>1600mg/kg, koma adzakhala hydrolyzed mu asidi mu thupi, kupewa kukhudzana. Sambani mutakumana. Oyendetsa ayenera kuvala magolovesi amphira.
