Bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) is a systemic herbicide, which is widely used for postemergence control of annual broadleaved weeds, especially young seedlings of cereals, ryegrass-seed crops, turf, and non-crop land: Sign in to download full-size image.
Bromoxynil octanoate E.C. (CAS 86702-80-9) Market Insights 2019, Global and Chinese Analysis and Forecast to 2024. Published On :15 May 2019 Report Code :GRS4011763 Category.
Abstract A method is described for the analysis of the herbicide bromoxynil and its octanoate in soils. Following extraction with aqueous acidic acetonitrile, the octanoate was separated from the phenolic bromoxynil by solvent partitioning.SUMMARY A widely used herbicide approved for use in the EU. It has a low aqueous solubility and a low volatility. There is a low potential for leaching to groundwater based on its chemical properties.In this paper, a simple, and rapid analysis of bromoxynil octanoate is reported for soil, corn leaves, and corn seeds by utilizing one-step liquid-liquid extraction and partitioning, followed by GC.
Identification of bromoxynil is performed by comparing the retention time of the chromatograph peak with that of an authentic standard. Compound identity is confirmed when the retention times agree, and when the response at a second wavelength agrees with the response at the primary wavelength. 2.3. Quantitative analysis is performed using an authentic standard of bromoxynil to produce a.
The abbreviation CIPAC stands for Collaborative International Pesticides Analytical Council. We are an international, non-profit-oriented and non-governmental organization (see Contact) devoted to promote the international agreement on methods for the analysis of pesticides and physico-chemical test methods for formulations and to promote interlaboratory programs for the evaluation of test.
A mixture of the known herbicide esters 3,5-dibromo-4-hydroxybenzonitrile (“bromoxynil” n-octanoate and bromoxynil n-heptanoate is provided having a molar ratio of n-octanoate n-heptanoate from 1:1.5 to 1.5:1, which mixture possesses an unexpectedly low melting point high solubility in hydrocarbon oils. Herbicidal compositions comprising bromoxynil n-octanoate and bromoxynil n-heptanoate.
The impurities such as octanoatyl chloride, bromoxynil acetate ester and chloroxynil octanoate ester in production of bromoxynil octanoate and their effects on bromoxynil octanoate are analyzed. The methods of preventing the occurance of impurities are found through experimental tests and the product quality is upgraded.

Bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) was continuously added to chernozem (Haplic typic) soil inoculated with a suspension ofPseudomonas putida capable of cometabolic decomposition of the compound in a heterocontinuous-flow cultivation setup. In the steady state, when glucose or ribose were simultaneously added, 90 and 47% of the added herbicide was degraded per day, respectively. If.
The octanoate ester of bromoxynil (3,5-dibromo-4-cyanophenyl octanoate), also an herbicide,. Samples were removed periodically for HPLC analysis and analysis of 14 C incorporation into biomass, as previously described. Briefly, samples were filtered, and the radioactivity associated with the filters (indicating 14 C incorporation into biomass) was determined by scintillation counting. To.
The developmental toxicity of the wide-spectrum herbicide bromoxynil (bromoxynil phenol; 3,5-dibromo-4-hydroxyphenyl cyanide) was evaluated in Sprague-Dawley rats and Swiss-Webster mice, and the developmental toxicity of its octanoate ester (2,6-dibromo-4-cyanophenyl octanoate) was evaluated in Sprague-Dawley rats. Animals were treated from Day 6 to Day 15 of gestation (presence of sperm or.
The invention relates to a weeding composition containing florasulam and bromoxynil octanoate. The weeding composition is mainly characterized by comprising the following effective components in percentage by weight: 1%-60% of the florasulam, 1%-80% of the bromoxynil octanoate and the balance of auxiliary agents and other excipients, and being prepared into wettable powder, water dispersible.
For occupational chemical analysis use NIOSH: Bromoxynil and Bromoxynil Octanoate, 5010. Bromoxynil Specification The Bromoxynil is an organic compound with the formula C 7 H 3 Br 2 NO.
