Dazomet CAS: 533-74-4

Ndi singano yoyera ngati kristalo, yopanda fungo, mp99.5 ℃ (kuvunda) (104 ~ 105 ℃). Kuthamanga kwa nthunzi 400 × 10-6Pa. Amasungunuka mosavuta mu acetone ndi chloroform; kusungunuka pang'ono mu ethanol ndi benzene; osasungunuka mu ether ndi carbon tetrachloride; kusungunuka m'madzi ndi 0,12% pa 25 ° C, ndipo kumawonjezeka pang'ono m'madzi ofunda. Ndiosavuta kuwola mu njira yamadzimadzi. Kuwola kumachulukitsidwa pamene kutentha kuli pamwamba pa 45 ℃, zomwe zimakhudza mphamvu ya wothandizira. Ndikosavuta kuwola mukakumana ndi asidi wamphamvu ndi alkali wamphamvu.

Amagwiritsidwa ntchito ngati mankhwala ophera tizilombo, ma fumigants, fungicides, etc.
