Carboxin Usage And Synthesis
Chemical PropertiesCarboxin is a white crystalline solid
UsesCarboxine is an fungicide used for the control of fruit rot of custard apple.
UsesSystemic plant fungicide.
UsesCarboxin is used as a seed treatment for cereals and as a seedling treatment on many cereals, beans, and vegetable crops and cotton. It is also used for the treatment of turf.
DefinitionChEBI: An anilide obtained by formal condensation of the amino group of aniline with the carboxy group of 2-methyl-5,6-dihydro-1,4-oxathiine-3-carboxylic acid. A fungicide for control of bunts and smuts normally that is normally used as a seed treatment.
General DescriptionOff-white crystals. Systemic fungicide and seed protectant.
Agricultural UsesFungicide: Carboxin is a General Use Pesticide (GUP) and is used as a seed protectant. It is often used in combination with other fungicides such as thiram or captan. Carboxin is a systemic anilide fungicide. It is used as a seed treatment for control of smut, rot, and blight on barley, oats, rice, cotton, vegetables, corn and wheat. It is also used to control fairy rings on turf grass. Carboxin may be used to prevent the formation of these diseases or may be used to cure existing plant diseases. Also used as a wood preservative.

Safety ProfilePoison by ingestion. Moderately toxic by skin contact and possibly other routes. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx and SOx.
Potential ExposureA potential danger to those involved in the production, Formulation and application of this systemic fungicide, seed protectant and wood preservative
Environmental FateBiological. The sulfoxidation of carboxin to carboxin sulfoxide by the fungus Ustilago maydis was reported by Bollag and Liu (1990).
Soil. Carboxin oxidized in soil forming carboxin sulfoxide. The half-life in soil was reported to be 24 hours (Worthing and Hance, 1991).
Plant. In plants (barley, cotton and wheat) and water, carboxin oxidizes to the corresponding sulfoxide (Worthing and Hance, 1991).

Metabolic pathwayCarboxin is a systemic fungicide which is very stable to hydrolysis but is readily oxidised at sulfur to a sulfoxide and a sulfone. The latter, oxycarboxin, is itself a commercial fungicide. Metabolism is mainly by oxidation at sulfur in soil, plants and animals but hydroxylation of the phenyl ring is also important in animals. Hydrolysis has been convincingly demonstrated only in plants (peanut).
ShippingUN2588 Pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.
DegradationCarboxin is stable to hydrolysis (25 °C) at pH 5,7 and 9. Measurable rates are seen only at higher pH and occur by nucleophilic attack by hydroxyl ion at carbonyl. The half-life in 0.5 N NaOH is 107 days. Thus chemical hydrolysis is not expected to be significant under environmental conditions (El-Dib and Aly, 1976).
The compound is very labile to aqueous photolysis with a DT50 of <3 hours (PM).
IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Avoid heat and humidity. Thermal decomposition products may include cyanide gas and cyanide salts.
Waste DisposalDissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
