Description
Chlorotoluron is a member of the class of ureas, specifically an N-methyl urea derivative with a 3-chloro-4-methylphenyl group at position 3 and a methyl group at position 1. It is a herbicide known for its selective action on certain types of weeds while being non-toxic to honeybees. However, it is considered moderately toxic to mammals, birds, earthworms, and most aquatic organisms.
Uses
Used in Agriculture:
Chlorotoluron is used as a herbicide for controlling various types of weeds in agricultural settings. Its selective action allows it to be effective against specific weed species without causing harm to the desired crop or beneficial insects like honeybees. This selective herbicidal property makes it a valuable tool in modern agriculture for maintaining crop health and yield.
Used in Environmental Management:
Due to its moderate toxicity to certain non-target organisms, Chlorotoluron can be used in environmental management practices to control invasive plant species or manage vegetation in ecologically sensitive areas. Its application in these contexts helps maintain ecological balance and protect native flora and fauna from the negative impacts of invasive species.
Metabolism
Chlortoluron is rapidly
metabolized in winter wheat. Hydroxylation of the methyl
group on the phenyl ring has been demonstrated as a
detoxification mechanism for chlortoluron resistance in
winter wheat, whereas in the susceptible weed blackgrass
(Alopecurus myosuroides Huds.), the main metabolite is
the mono N-demethylated metabolite (107). In a tolerant
weed, Persian speedwell (Veronica persica Poir.), chlortoluron is rapidly transformed to the nonphytotoxic di-N-demethylated metabolite (107).
Check Digit Verification of cas no
The CAS Registry Mumber 15545-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,4 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15545-48:
(7*1)+(6*5)+(5*5)+(4*4)+(3*5)+(2*4)+(1*8)=109
109 % 10 = 9
So 15545-48-9 is a valid CAS Registry Number.
