Description
Fluometuron is a phenylurea-based herbicide, which is a white crystalline solid with a melting point of 163-164°C. It is readily soluble in organic solvents and partially soluble in water. Fluometuron is often used in liquid solution and may be flammable.
Uses
Used in Agriculture:
Fluometuron is used as a herbicide for controlling many annual broad-leaved weeds in sugarcane and cotton crops. It is a selective herbicide that acts on susceptible plants by inhibiting photosynthesis. The EPA has registered Fluometuron exclusively for use on cotton and sugarcane. It can be applied pre-emergence, for weed control before planting, or post-emergence, after target crops and weeds come up, and may have residual activity for several months. Fluometuron is available in liquid, dry flowable, and wettable powder formulations.
Reactivity Profile
Fluometuron is a trifluoromethyl urea derivative. May react with hypochlorites to form nitrogen trichloride which explodes spontaneously in air [J. Am. Chem. Soc. 63:3530-32]. May reacts with azo and diazo compounds to generate toxic gases. Reacts with strong reducing agents to form flammable gases.
Hazard
Toxic by ingestion. Questionable carcinogen.
Health Hazard
SYMPTOMS: Symptoms of exposure to Fluometuron may include possible convulsions or coma; irritation to the skin, gastrointestinal tract, respiratory tract; and lowered blood pressure.
Fire Hazard
Flash point data are not available for Fluometuron, but Fluometuron is probably combustible.

Potential Exposure
This material is used as a herbicide.
Environmental Fate
Soil. In soils, ?uometuron rapidly degrades (half-life approximately 30 days) to carbon dioxide, polar and nonextractable compounds (Hartley and Kidd, 1987; Humburg et al., 1989).Groundwater. According to the U.S. EPA (1986) ?uometuron has a high potential to leach to groundwaterPlant. In plants, ?uometuron degrades to a demethylated intermediate which subsequently is degraded to the aniline moiety (possibly m-tri?uoromethylaniline) (Hartley and Kidd, 1987; Humburg et al., 1989). Duke et al. (1991) reported that ?uometurChemical/Physical. Emits toxic fumes of nitrogen oxides and ?uorine when heated to decomposition (Sax and Lewis, 1987).

Incompatibilities
Liquid solutions are incompatible with
oxidizers (chlorates, nitrates, peroxides, permanganates,
perchlorates, chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Keep away from alkaline materi als, strong bases, strong acids, oxoacids, epoxides.
Check Digit Verification of cas no
The CAS Registry Mumber 2164-17-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2164-17:
(6*2)+(5*1)+(4*6)+(3*4)+(2*1)+(1*7)=62
62 % 10 = 2
So 2164-17-2 is a valid CAS Registry Number.

Preparation of N,N-Dimethyl-N′-arylureas using S,S-dimethyl dithio-carbonate as a carbonylating reagent
Degani, Iacopo,Fochi, Rita,Magistris, Claudio,Migliaccio, Mara
experimental part, p. 801 - 808 (2009/08/07)
A new, general method for the preparation of N,N-di-methyl-N′- arylureas using S,S-dimethyl dithiocarbonate as a phosgene substitute is reported. The method has been set up according to four procedures, all including three steps: (1) reaction of S,S-di- methyl dithiocarbonate with dimethylamine to give S-methyl N,N-dimethylthiocarbamate; (2) halogenation with various halogenating reagents (chlorine, methanesulfenyl chloride, bromine, and meth-anesulfenyl bromide) to give N,N-dimethylcarbamoyl chloride or bromide; (3) in situ reaction with primary arylamines. All the target products were obtained in high yields (85-98%; 16 reactions, average yield 93%) and with high purity. Also noteworthy is the recovery of byproducts of industrial interest, namely methanethiol and dimethyl disulfide, with complete exploitation of the reagent S,S- dimethyl dithiocarbonate.
