330-55-2 Usage
Description
Linuron is a white crystalline compound that is odorless and has very low solubility in water. It can be ingested through contaminated food or water or come into contact with the skin, potentially causing nausea, vomiting, diarrhea, and eye irritation. While there is limited evidence on the effects of exposure to linuron on human health, it is unlikely to have any adverse effects at normal background levels.
Uses
Used in Agriculture:
Linuron is used as a selective pre-emergence and post-emergence herbicide for a wide variety of food crops. It is effective in controlling many annual broad-leaved and grass weeds, ensuring healthy crop growth and increased yields.
Used in Soybean, Cotton, Potato, and Other Crops:
Linuron is applied as a preand post-emergent herbicide in crops such as soybean, cotton, potato, corn, bean, pea, winter wheat, asparagus, carrot, and fruit crops. It works by inhibiting photosynthesis in target weed plants, thus promoting the growth of desired crops.
Used in Stored Crop Protection:
Linuron is also utilized in warehouses and storerooms to control annual and perennial broadleaf and grassy weeds on stored crops, preventing damage and maintaining the quality of the stored produce.
Regulation:
The US Environmental Protection Agency (EPA) classifies Linuron as a Restricted Use Pesticide (RUP), indicating that its use is limited and requires specific knowledge and precautions to minimize potential risks to human health and the environment.
Air & Water Reactions

farming. Vlihen heated to decomposition it
emits very toxic fumes of Cl and NOx. See

DIMETHYLUREA.
Potential Exposure
Inhibits photosynthesis. Linuron is a
selective, pre-emergence urea herbicide used to control
grasses and broadleaf weeds in carrots, beans, peas, asparagus, maize, potatoes, soybeans, sorghum, wheat, bananas,
coffee, cotton, and ornamentals. It is also used for control
of annual weeds in storehouses, roadsides, fence rows and
other noncrop lands. Linuron is frequently used in formulations with other herbicides, insecticides, and fungicides
Environmental Fate
Soil. Linuron degraded in soil forming the common metabolite 3,4-dichloroaniline
(Duke et al., 1991). In an aerobic, biologically active, organic-rich, pond sediment, linuron
was converted to the intermediate 3-(3-chlorophenyl)-1-methoxymethylurea. This compound
further degraded to unidentified compounds (Stepp et al., 1985).Linuron was degraded by Bacillus sphaericus in soil forming N,O-dimethylhydroxylamine
and carbon dioxide (Engelhardt et al., 1972). Only 1 ppm 3,4-dichloroaniline was
identified in soils after incubation of soils containing 500 ppm linuron (Belasco and PeThe half-lives for linuron in soil incubated in the laboratory under aerobic conditions
ranged from 56 to 88 days with an average of 75 days (Moyer et al., 1972; Hance, 1974;
Usorol and Hance, 1974). In field soils, the average half-life for linuron was 8Plant. Undergoes demethylation and demethoxylation in plants (Hartley and Kidd,
1987). Metabolites identified in carrots 117 days after treatment were 3,4-dichlorophenylurea,
3-(3,4-dichlorophenyl)-1-methylurea and 3,4-dichloroaniline. About 87% of the
linuron remained unreacted (Loekke, 1974).Photolytic. When an aqueous solution of linuron was exposed to summer sunlight for
2 months, 3-(3-chloro-4-hydroxyphenyl)-1-methoxy-1-methylurea, 3,4-dichlorophenylurea
and 3-(3,4-dichlorophenyl)-1-methylurea formed at yields of 13, 10 and 2%, re

Toxicity evaluation
As a reproductive and developmental toxicant, linuron works
via androgen receptor antagonist activity; that is, it competes
with testosterone for binding to the androgen receptor. In
mouse tissues, linuron competitively blocked transcription
through androgen receptor induced by dihydrotestosterone in
a concentration-dependent manner.
Incompatibilities
Amides are incompatible with oxidizers
(chlorates, nitrates, peroxides, permanganates, perchlorates,
chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, and epoxides. Similar organic
amides react with azo and diazo compounds, releasing
toxic gases. Contact with reducing agents can release flammable gases. Amides are very weak bases but they can
react as acids, forming salts. Mixing amides with dehydrating agents such as such as phosphorus pentoxide or thionyl
chloride generates the corresponding nitrile
Waste Disposal

Check Digit Verification of cas no
The CAS Registry Mumber 330-55-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 330-55:
(5*3)+(4*3)+(3*0)+(2*5)+(1*5)=42
42 % 10 = 2
So 330-55-2 is a valid CAS Registry Number.
