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).
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device

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

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).
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.
