Guryaha
Alaabta saafiga ah waa crystal aan midab lahayn oo aan lahayn ur. Si fudud u milmi kara benzene, chloroform (230g / L), acetone (80g / L, carbon disulfide iyo dareerayaasha kale ee organic, wax yar ku milma ether iyo ethanol (<10g / L), oo aan biyo ku milmin (30mg / L), oo ku milmay acid, midabku waa caddaan ama budo huruud ah.
Shaqada
Xawaaraha caagga ah ee TMTD waa dardar labaad aad u fiican oo loogu talagalay xawaareyaasha nooca thiazol. Waxa kale oo lala isticmaali karaa dardar-geliyayaal kale si loo dardargeliyo walxaha colloidal vulcanization joogto ah. Caadi ahaan, waxa kale oo loo isticmaali karaa iyada oo lagu daray dardargeliyaha MBT(M). Burburinta caagga butyl asal ahaan waa la mid. Xawaareeyaha waxaa inta badan loo adeegsadaa sameynta taayirrada, tuubooyinka gudaha, kabaha caagga ah, sahayda caafimaadka, fiilooyinka, alaabada caagga warshadaha, iwm. Waxaa loo isticmaalaa fungicide iyo cayayaanka beeraha, sidoo kale waxaa loo isticmaali karaa wax lagu daro.
