533-74-4 Usage
Description
Dazomet is a biocide used to control bacterial and
fungal growth in pulp and paper systems, but 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.
Uses
Different sources of media describe the Uses of 533-74-4 differently. You can refer to the following data:
1. Soil fungicide; nematocide; herbicide; insecticide; soil sterilant.
2. Dazomet is a multi-purpose soil fumigant used for the control of
nematodes, soil fun@, soil insects and weed seeds. It is also used as a
slimicide in pulp and paper manufacture and as a preservative of
adhesives.
3. Dazomet is a as fumigant used for the control of brown root rot disease. Dazomet was shown to be a possible agent in preventing pest incursion in agriculture, gardening and agroforestry.
4. Soil fungicide, nematocide, weed killer; slimicide in paper making.
Definition
ChEBI: A dithiocarbamic ester that is 1,3,5-thiadiazinane with a thione moiety at position 2 and in which the hydrogens attached to the nitrogens are replaced by methyl groups. A fungicide, herbicide and nematicide, it is used prior to sowing or planting for the
ontrol of soil fungi, nematodes, bacteria and germinating weeds, and as fumigant for poultry litter and eggs to control Salmonella. It is a non-ozone-depleting alternative to methyl bromide.
General Description
White crystals or off-white powder. Pungent, acrid odor.
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.
Shipping
UN3077 Environmentally hazardous substances,
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.
