2,6-Dichloro-4-nitroaniline Chemical Properties,Uses,Production

Description

Dicloran is a protective fungicide. It has a low aqueous solubility and is volatile. Based on its chemical properties, it may leach to groundwater. It can also be quite persistent in soils but not usually so in water. It is moderately toxic to mammals but is not expected to bioaccumulate. Exposure may damage reproduction and/or development. Dicloran is moderately toxic to most aquatic organisms, birds, honeybees and earthworms.

Chemical Properties

yellow granular powder and chunks

Chemical Properties

Dicloran is a yellow crystalline solid or power. Odorless.

Uses

Dichloran is a component for pesticide formulations.

Uses

Dicloran is a protectant fungicide used to control various rots pathogens (Botrytis, Monilinia, Rhizopus and Sclerotinia) in a wide variety of fruits and vegetables.

Uses

It is used as dyestuff, agricultural and pharmaceutical intermediate.

Definition

ChEBI: A nitroaniline that is 4-nitroaniline in which the hydrogens at positions 2 and 6 are replaced by chlorines. An agricultural fungicide, it is not approved for use in the European Union.

Agricultural Uses

Fungicide: Used to control fungi on a variety of crops. The top crop usages in California are on celery, head lettuce, and grapes (table, wine and raisin). Not approved for use in EU countries. Actively registered in the U.S. Sixty-five global suppliers.

Mechanism of action

Protective, contact action, thought to act by inhibiting respiration inhibiting spore germination. Lipid peroxidation inhibitor.

Synthesis

100-01-6

99-30-9

The general procedure for the synthesis of 2,6-dichloro-4-nitroaniline from 4-nitroaniline was as follows: 30 mL of the mother liquor obtained in step 1) was added to a 500 mL three-necked flask with 13.8 g (0.1 mol) of p-nitroaniline, and the mixture was cooled down to 10 °C under mechanical stirring. Subsequently, 25.5 mL of 30% hydrogen peroxide solution (dried and processed at 20°C) was slowly added dropwise for 2 hours. Upon completion of the reaction, the mixture was allowed to stand at room temperature until a solid precipitate precipitated. The filter cake and the filtrate were separated by filtration, and the filter cake was dried at 65 °C for 4 hours to give 20.5 g of 2,6-dichloro-4-nitroaniline in 99.0% yield. The volume of the filtrate collected in step 3) was about 240 mL, and the concentration of HCl in the filtrate was measured to be 25.8% by titration using 1 mol/L sodium hydroxide standard solution.

Potential Exposure

Dichloran is a substituted benzene/ chlorophenyl fungicide Used to control fungi on a variety of crops. The top crop usages in California are on celery, head lettuce, and grapes (table, wine and raisin).

Metabolic pathway

The metabolism of 2,6-dichloro-4-nitroaniline (DCNA) in rat hepatic microsomes gives rise to the unique metabolite 3,5-dichloro-4-aminophenol (DCAP).

Shipping

UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

Purification Methods

Crystallise Dichloran from aqueous EtOH or *benzene/EtOH. [Beilstein 12 IV 1681.]

Degradation

Dicloran (1) is stable to hydrolytic degradation (pH 5-9) up to 300 °C. Degradation occurred when dicloran in pH 7 solution was irradiated with UV light (>290 nm); the estimated DT₅₀ was 41 days (PM). Smith-Downey and Fordham (1990) reported the hydrolysis of dicloran in 6 M base to yield 3,5-dichloro-4-aminophenol(2) as the only product detected.

Incompatibilities

Keep away from strong oxidizing agents, strong acids; acid anhydrides; acid chlorides; acetic anhydride; and carbon dioxide

Waste Disposal

Consult with a licensed waste disposal service or environmental regulatory agencies for guidance on acceptable disposal practices. Dissolve or mix material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber
