Monosulfuron Chemical Properties, Uses, Production

Chemical Properties

It is soluble in water under alkaline condition, stable under neutral and weak alkaline condition, easy to be hydrolyzed under strong acid and strong alkaline condition. It is more stable in tetrahydrofuran and acetone, less stable in methanol, and extremely unstable in N,N-dimethylformamide. The effect of temperature on the stability of monomethylsulfuron is greater than that of light.

Uses

Monosulfuron is a sulfonylurea herbicide that inhibits Acetohydroxyacid synthase enzyme.

Production Methods

Monosulfuron is produced through a multi step synthesis typical of sulfonylurea herbicides, involving construction of the heteroaromatic ring and coupling with a sulfonylurea moiety. The process begins with preparation of a substituted pyrimidine intermediate, which is functionalised through nitration and amination steps to introduce the required heteroatoms. In parallel, a sulfonyl isocyanate or related activated sulfonyl reagent is synthesised. These intermediates are then coupled under controlled conditions to form the sulfonylurea linkage, yielding monosulfuron.

Agricultural Uses

Two compounds, monosulfuron and methiopyrsulfuron (NPC-C9908), developed by research groups in China, are currently marketed in China. Outside mainland China, only limited public knowledge is available concerning these compounds.
Monosulfuron (CAS no.: 155860-63-2) is a new herbicide for the control of weeds in wheat (T. aestivum) and millet (Panicum miliaceum and Setaria italica), with application rates ranging from 15 to 60 g a.i. ha−1. The molecule was discovered by Nankai University in 1993 and registered in China. Monosulfuron provides effective control of various broadleaf and grass weeds, such as Leptochloa chinensis, Amaranthus retroflexus, C. album, Abutilon theophrasti, Xanthium sibiricum Patrin., Portulaca oleracea, Acalypha australis, Solanum nigrum, Digitaria sanguinalis, Descurainia sophia, Echinochloa phyllopogon, Eriochloa villosa, and Puccinellia distans. Further properties and environmental data of monosulfuron have been described in several reports by Fan et al. and Wang et al. Interestingly, monosulfuron-ester sodium was recently reported as an efficient chemical-hybridizing agent for B. napus at a concentration of approximately 1% of that needed for herbicidal activity.

Mechanism of action

Inhibits the enzyme acetolactate synthase (ALS)
