    Isicelo

    1.Embonini yezemithi, isetshenziselwa ukukhiqiza i-lumina, i-barbital, i-vitamin B1, i-vitamin B2, i-vitamin B6, i-phenylbutazone, i-amino acids, njll.

    2.Iwumuthi ophakathi nendawo wesikhunta i-Isoprothiolane kanye nesilawuli sokukhula kwezitshalo i-indomethacin.

    3.Isetshenziselwa i-perfume, i-adhesive, i-resin additive, i-electroplate polishing agent kanye ne-welding flux additive.

    Impahla

    Iyancibilika emanzini, incibilika ku-ethanol ne-ether ne-pyridine.

    Isitoreji

    Igcinwe endaweni eyomile, enomthunzi, nendawo engenawo umoya.

    Ukuzinza

     
    1. Izinzile ngaphansi kwezinga lokushisa elivamile nokucindezela.
     
     
    Izinto ezingahambelani: i-alkali, i-oxidizing agent, i-ejenti yokunciphisa.
     
     
    2. Ubuthi obuphansi. Inomphumela ovuselelayo esikhumbeni kanye nolwelwesi lwamafinyila, kodwa ayibucayi njenge-oxalic acid. I-LD50 yomlomo yamagundane ingu-1.54g/kg. Ukuvikela okukhethekile ngokuvamile akudingekile lapho kukhiqizwa i-malonic acid, kodwa i-cyanoacetic acid ne-sodium cyanide zombili ziwushevu obunamandla, ngakho-ke kufanele uqaphele ikakhulukazi lapho uphatha izinhlanganisela eziqukethe amaqembu e-cyano, ugqoke okokulwa namagciwane, futhi uthuthukisa izindlela zokuphepha ezihambisanayo.
     
     
    3. Itholakala emaqabunga kagwayi aphekwe ngomkhuhlane, amahlamvu kagwayi we-burley kanye nentuthu evamile.
     
     
    4. Ingafakwa ngaphansi kwe-vacuum.
