533-74-4 Usage
Description
Dazomet is a biocide used to control bacterial and fungal growth in various applications, including agriculture and pulp and paper systems. It is a white crystalline or off-white powder with a pungent, acrid odor. Dazomet is a dithiocarbamic ester with a 1,3,5-thiadiazinane structure and a thione moiety at position 2, where the hydrogens attached to the nitrogens are replaced by methyl groups.
Uses
Used in Agriculture:
Dazomet is used as a soil fungicide, nematocide, and herbicide for the control of soil fungi, nematodes, bacteria, and germinating weeds. It is also used as a soil sterilant and insecticide, as well as a fumigant for poultry litter and eggs to control Salmonella. Dazomet is a non-ozone-depleting alternative to methyl bromide and is used prior to sowing or planting.
Used in Pulp and Paper Industry:
Dazomet is used as a slimicide in the pulp and paper industry to control bacterial and fungal growth. It is also used as a preservative for adhesives.
Used in Preventing Pest Incursion:
Dazomet is used as a fumigant to control brown root rot disease and as a possible agent in preventing pest incursion in agriculture, gardening, and agroforestry.
Dazomet is contained in products such as Busan 1058, Mylone, and Fungicide 974 (Crag). Sensitization to Dazomet has been rarely reported, with one case occurring in a paper-mill worker.
Air & Water Reactions
Insoluble in water. Slowly hydrolyzed.
Reactivity Profile
Dazomet decomposes in water, dilute acids and alcohol.
Fire Hazard
Flash point data for Dazomet are not available; however, Dazomet is probably combustible.
Contact allergens
Dazomet is a biocide used to control bacterial and fungal growth in a pulp and paper system, and also in agriculture for soil disinfection. It is contained in Busan 1058, Mylone, and Fungicide 974 (Crag?). Sensitization, rarely reported, occurred in a paper mill worker.
Safety Profile
Poison bj 7 in ' g estion and
intraperitoneal routes. Moderately toxic by
skin contact and subcutaneous routes. A
severe eye irritant. A mild primary skin
irritant and sensitizer. When heated to
decomposition it emits very toxic fumes of
NOx and SOx
Environmental Fate
Soil. Soil metabolites include formaldehyde, hydrogen sulfide, methylamine and
methyl(methylaminomethyl)dithiocarbamic acid (Hartley and Kidd, 1987) which further
decomposes to methyl isothiocyanate (Harley and Kidd, 1987; Ashton and Monaco, 1991;
Cremlyn, 1991). The rate of decomposition is dependent upon the soil type, temperature
and humidity (Cremlyn, 1991).Chemical/Physical. Hydrolyzes in acidic solutions forming carbon disulfide, methylamine and formaldehyde (Hartley and Kidd, 1987; Humburg et al., 1989). These compounds are probably formed following the decomposition of dazomet with alcohol and
Metabolic pathway
Dazomet is a propesticide that decomposes to generate the highly volatile
methyl isothiocyanate. The pathways of metabolism of methyl isothiocyanate
are described under its own entry. In soil, dazomet degrades mainly
via a dithiocarbamic acid which in turn affords methyl isothiocyanate,
formaldehyde, hydrogen sulfide and methy lamine.

solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous
hazardous material, Technical Name Required.
Degradation
Dazomet is rapidly hydrolysed in acidic media to carbon disulfide, formaldehyde
and methylamine (PM). DT50 values for hydrolysis were 85,
490 and 110 hours at pH 5,7 and 9, respectively. It is sensitive to oxygen
and to light.
Check Digit Verification of cas no
The CAS Registry Mumber 533-74-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 533-74:
(5*5)+(4*3)+(3*3)+(2*7)+(1*4)=64
64 % 10 = 4
So 533-74-4 is a valid CAS Registry Number.
