1134-23-2 Usage
Chemical Properties
Cycolate is an oily, clear, or amber to yellow
liquid. Aromatic odor;
Uses
Herbicide used to control several broad-leaved weeds and many annual grasses in
sugar beets, table beets and spinach
General Description
Colorless liquid with an aromatic odor. Used as a selective systemic herbicide.
Air & Water Reactions
Thio and dithiocarbamates slowly decompose in aqueous solution to form carbon disulfide and methylamine or other amines. Such decompositions are accelerated by acids or alkalis.
Reactivity Profile
CYCLOATE is a thiocarbamate ester. Flammable gases are generated by the combination of thiocarbamates and dithiocarbamates with aldehydes, nitrides, and hydrides. Thiocarbamates and dithiocarbamates are incompatible with acids, peroxides, and acid halides.
Flammability and Explosibility
Nonflammable
Agricultural Uses
Herbicide: Used to control broadleaf weeds, annual and perennial grasses and nutgrass in spinach, beets, and sugar
beets. Not approved for use in EU countries. Actively
registered in the U.S.

Potential Exposure
Cycolate is a thiocarbamate herbicide
used to control broad leaf weeds, annual and perennial
grasses and nutgrass in spinach, beets, and sugar beets.
Environmental Fate
Soil. The reported half-life in soil is approximately 4–8 weeks (Hartley and Kidd,
1987)Groundwater. According to the U.S. EPA (1986) cycloate has a high potential to leach
to groundwaterPlant. Cycloate is rapidly metabolized in sugarbeets to carbon dioxide, ethylcyclohexylamine, sugars, amino acids and other natural constituents (Humburg et al., 1989)Chemical/Physical. In the gas phase, cycloate reacts with hydroxyl and NO3 radicals
but not with ozone. With hydroxy radicals, cleavage of the cyclohexyl ring was suggested
leading to the formation of a compound tentatively identified as C2H5(CHO)NC(O)SC2H5.
The calculated photolysis lifetimes of cycloate in the troposphere with hydroxyl and NO3
radicals are 5.2 hours and 1.4 days, respectively (Kwok et al., 1992).

Incompatibilities
Cycolate reacts violently with powerful
oxidizers such as calcium hypochlorite. Thiocarbamate
esters are combustible. Poisonous gases are generated by
the thermal decomposition of thiocarbamate compounds,
including carbon disulfide, oxides of sulfur, oxides of nitro-
gen, hydrogen sulfide, ammonia, and methylamine. Thio
and dithiocarbamates slowly decompose in aqueous solu-
tion to form carbon disulfide and methylamine or other
amines. Such decompositions are accelerated by acids.
Flammable gases are generated by the combination of thio-
carbamates with aldehydes, nitrides, and hydrides.
Thiocarbamates are incompatible with acids, peroxides, and
acid halides.
Waste Disposal
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved landfill.
Consult with environmental regulatory agencies for guid-
ance on acceptable disposal practices. Incineration with
effluent gas scrubbing is recommended. Containers must be
disposed of properly by following package label directions
or by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
Check Digit Verification of cas no
The CAS Registry Mumber 1134-23-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1134-23:
(6*1)+(5*1)+(4*3)+(3*4)+(2*2)+(1*3)=42
42 % 10 = 2
So 1134-23-2 is a valid CAS Registry Number.

Practical synthesis of S-alkyl thiocarbamate herbicides by carbonylation of amines with carbon monoxide and sulfur
Mizuno, Takumi,Iwai, Toshiyuki,Ito, Takatoshi
, p. 2869 - 2873 (2007/10/03)
An industrial and economic carbonylation of amines with carbon monoxide and sulfur has been developed for the synthesis of S-alkyl thiocarbamate herbicides. In the presence of potassium carbonate and solvent DMSO, S-alkyl thiocarbamates, such as thiobencarb and orbencarb (herbicides) are synthesized in excellent yields from amines, carbon monoxide, sulfur, and alkyl halides under mild conditions (1atm, 20°C).

Novel oxime ethers and oxime esters of the formula I given herein have various advantageous effects with regard to stimulation of plant growth, particularly in the early stage of development of the plant. Furthermore, such compounds have the property of rendering, in the sense of an antidote action, agricultural chemicals which would otherwise damage the plants (phytotoxic chemicals) more compatible with the cultivated plants. Herbicides that are insufficiently selective can be used for example in the presence of such oxime derivatives in specific cultivated crops for combating weeds, without disadvantageous consequences for the cultivated plants.
Process for the preparation of substituted S-alkyl thio-carbamates
-
, (2008/06/13)
The invention relates to a new and advantageous process for the preparation of substituted S-alkyl thiocarbamates having the general formula (I), EQU1 wherein R1 stands for a C1-4 alkyl group, R2 stands for a C1-4 alkyl or cyclohexyl group, or R1 and R2 may form together a C4-6 polymethylene group, and R3 stands for a C2-3 alkyl group. In accordance with the invention the substituted O-alkyl thiocarbamates of the general formula (II), EQU2 wherein R1, R2 and R3 each have the same meanings as defined above, are subjected to isomerization by heating them at a temperature of 130° to 180°C in the presence of dimethyl sulfate or diethyl sulfate to yield the appropriate S-alkyl esters.
