Description
Azimsulfuron is a sulfonylurea-based herbicide, specifically designed for the control of broadleaf weeds in rice fields. It was introduced in 1996 by DuPont and is known for its effectiveness against a wide range of weeds, including hard-to-control perennials. Azimsulfuron is sold under the trade names "Gulliver" and "Azin."
Used in Agricultural Industry:
Azimsulfuron is used as a herbicide for the control of broadleaf weeds, including hard-to-control perennials, in rice fields. It is effective at application rates of 8-20 g a.i. ha-1, providing superior weed control compared to the first-generation sulfonylurea bensulfuron at 50-75 g a.i. ha-1. It is targeted to replace or supplement bensulfuron in some applications.
In Japan, azimsulfuron is used as a premixture with bensulfuron (6 + 30 g a.i. ha-1) to boost the activity against perennial weeds. It has shown good control of various members of the Echinochloa family, such as E. crus-galli, E. hispidula, E. oryzicola, and E. oryzoides. Other weeds controlled by azimsulfuron include Alisma lanceolatum, A. plantago-aquatica, Butomus umbellatus, Cyperus difformis, Scirpus maritimus, S. mucronatus, S. supinus, Heteranthera limosa, Potamogeton nodosus, Ammannia coccinea, A. robusta, Bergia capensis, and Lindernia dubia.
Used in Analytical Chemistry:
Azimsulfuron may be used as an analytical reference standard for the determination of the pesticide in various water samples. It can be analyzed in paddy field water by direct injection using liquid chromatography-hybrid triple quadrupole-linear ion trap-mass spectrometry (LC-QqLIT-MS). Additionally, tap and leaching water samples can be analyzed by solid-phase extraction (SPE), followed by LC coupled to tandem mass spectrometry (LC-MS/MS).
Safety Profile
Low toxicity by ingestion,inhalation, skin contact, and intraperitoneal routes. A mildeye irritant. When heated to decomposition it emits toxicvapors of NOx and SOx.
Safety Profile
Very unstable, explosivecompound. Very sensitive to heat. Samples have explodedduring analytical combustion. When heated todecomposition it emits toxic fumes of NOx. See AZIDES.
Check Digit Verification of cas no
The CAS Registry Mumber 120162-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,1,6 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120162-55:
(8*1)+(7*2)+(6*0)+(5*1)+(4*6)+(3*2)+(2*5)+(1*5)=72
72 % 10 = 2
So 120162-55-2 is a valid CAS Registry Number.
