The CAS Registry Mumber 142994-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,9 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 142994-06:
(8*1)+(7*4)+(6*2)+(5*9)+(4*9)+(3*4)+(2*0)+(1*6)=147
147 % 10 = 7
So 142994-06-7 is a valid CAS Registry Number.

Soil metabolism of isoxaflutole in corn

Rouchaud,Neus,Eelen,Bulcke

, p. 280 - 285 (2002)

The herbicide isoxaflutole 1 (5-cyclopropyl-4- isoxazolyl)[2-(methylsulfonyl)-4-(trifluoromethyl)phenyl]- methanone) has been applied preemergence at the rate of 125 g ha-1 on corn crops grown on fields located in regions different as to their soil textures. Its metabolite diketonitrile 2(2-cyano-3-cyclopropyl-1- (2-methylsulfonyl-4-trifluoromethylphenyl)-propane-1,3-dione) - which is the herbicide's active compound - and its nonherbicide metabolite 3 (2-methylsulfonyl-4-trifluoromethylbenzoic acid) were measured in the 0-10 cm surface soil layer of the corn crops after the treatment and until the harvest. At the opposite of what occurred in plant shoots, the transformation of isoxaflutole 1 into diketonitrile 2 was not immediate in soil. In the 0-10 cm surface soil layer, this transformation occurred progressively according to an apparent second-order kinetics, and the soil half-lives of isoxaflutole 1 self were comprised between 9 and 18 days. The adsorption of isoxaflutole 1 onto the solid phase of the soil and its organic matter should explain the stabilization effect of soil, increased by the application of fresh organic fertilizer. The sum of the concentrations of isoxaflutole 1 and diketonitrile 2 disappeared in the 0-10 cm surface soil layer according to an apparent first-order kinetics, and the soil half-lives of this sum were comprised between 45 and 65 days. The sum of the concentrations of isoxaflutole 1 and of its metabolites diketonitrile 2 and acid 3 did not account for the amount of isoxaflutole 1 applied. The discrepancy increased with the delay after the application, showing that the acid 3 was further metabolized in soil into common nontoxic products, and ultimately into CO2. The conjunction of the adsorption of isoxaflutole and its metabolites (which reduced their mobilities) onto the soil and its organic matter, and their further metabolism should explain why isoxaflutole and its metabolites were not detected in the 10-15 and 15-20 cm surface soil layers during the crops.

Reaction pathways of the diketonitrile degradate of isoxaflutole with hypochlorite in water

Lerch,Lin,Leigh

, p. 1893 - 1899 (2007)

Isoxaflutole (IXF; Balance) belongs to a new class of isoxazole herbicides. Isoxaflutole has a very short half-life in soil and rapidly degrades to a stable and phytotoxic degradate, diketonitrile (DKN). DKN was previously discovered to rapidly react with

Cleavage of the diketonitrile derivative of the herbicide isoxaflutole by extracellular fungal oxidases

Mougin,Boyer,Caminade,Rama

, p. 4529 - 4534 (2007/10/03)

Isoxaflutole is a herbicide activated in soils and plants to its diketonitrile derivative, the active herbicide principle. The diketonitrile derivative undergoes cleavage to the inactive benzoic acid analogue. In this paper, it is established that an oxidative mechanism implicating two successive reactions in the presence of dimethyldioxirane can chemically initiate the cleavage of the diketonitrile. It is also shown that two white rot strains, Phanerochaete chrysosporium and Trametes versicolor, are able to convert the diketonitrile to the acid when cultured in liquid media. This main metabolite amounts to 24.6 and 15.1% of initial herbicide content after 12-15 days of culture. Another polar metabolite represents a time course similar to that of diketonitrile degradation. Purified laccase (EC 1.10.3.2), in the presence of 2 mM 2,2'-azinobis(3-ethylbenzthiazoline-6-sulfonic acid) acting as a redox mediator at pH 3 supports the reaction with rates of 0.3-0.4 nmol h-1 unit-1.
