Demosan Chemical Properties,Uses,Production

Chemical Properties

beige powder

Chemical Properties

Colorless crystalline solid. Musty odor


ChEBI: A dimethoxybenzene that is p-dimethoxybenzene which is substituted by chlorines at positions 2 and 5. A fungicide formerly used as a seed treatment, it is not approved for use in the European Union.

General Description

White to tan solid or beige powder. Musty odor.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Demosan is stable at temperatures up to 514° F, in water in the presence of dilute acids or alkalis, and in the common organic solvents. Demosan is subject to microbial decomposition in soil under moist conditions.

Fire Hazard

Demosan is combustible.

Agricultural Uses

Fungicide: A systemic fungicide used to control snow mold on turf grass; used on cotton, sugar beets and bean seeds to control seedling disease. Not approved for use in EU countries. Registered for use in the U.S. except California

Trade name


Potential Exposure

An organochlorine/substituted benzene systemic fungicide used to control snow mold on turf grass; used on cotton, sugar beets and bean seeds to control seedling disease. Not approved for use in EU countries.

First aid

Speed in removing material from eyes and skin is of extreme importance. Eyes: Eye contact can cause dangerous amounts of these chemicals to be quickly absorbed through the mucous membrane into the bloodstream. Directly, irrigate with large amounts of plain, tepid water or saline for 20 minutes, occasionally lifting the lower and upper lids. During this time, remove contact lenses, if easily removable without additional trauma to the eye. Get medical aid immediately. Have physician check for possible delayed damage. Skin: Get medical aid. Dermal contact can cause dangerous amounts of these chemicals to be absorbed into the bloodstream. Wearing the appropriate PPE equipment and respirator for organochlorine pesticides, immediately flush exposed skin, hair, and under nails with plain, running, tepid water for 20 minutes, then wash twice with mild soap. Shampoo hair promptly if contaminated; protect eyes. Do not scrub skin or hair, since this can increase absorption through the skin. Rinse thoroughly with water. Victims who are able and cooperative may assist with their own decontamination. Remove and doublebag contaminated clothing and personal belongings. Leather absorbs many organochlorines; therefore, items such as leather shoes, gloves, and belts should be discarded. If the skin is swollen or inflamed, cool affected areas with cold compresses. Ingestion: Call poison control. Loosen all clothing. Never give anything by mouth to an unconscious person. Get medical aid. Do not induce vomiting.  In cases of ingestion, the patient is at risk of central nervous system depression or seizures, which may lead to pulmonary aspiration during vomiting. If the victim is conscious and able to swallow, administer an aqueous slurry of activated charcoal at 1 g/kg (usual adult dose 6090 g, child dose 2550 g). A soda can and straw may be of assistance when offering charcoal to a child. The efficacy of activated charcoal for some organo chlorine poisoning (such as chlordane) is uncertain. If victim is unconscious or having convulsions, do nothing except keep victim warm. In some cases you may be specifically instructed by Poison Control to induce vomiting by way of 2 tablespoons of syrup of ipecac (adult) washed down with a cup of water. Do not give activated charcoal before or with ipecac syrup. Inhalation: Get medical aid. Do not contaminate yourself. Wearing the appropriate PPE equipment and respirator for organochlorine pesticides, immediately remove the victim from the contaminated area to fresh air. For inhalation exposures, monitor for respiratory distress. If the victim is not breathing, administer artificial respiration. Do not use mouth-tomouth 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. If cough or breathing difficulty develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. If breathing is difficult, administer 100% humidified supplemental oxygen through bag/mask apparatus until medical help arrives. Do not leave victim unattended.


UN2761 Organochlorine pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials. UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.


May react with strong oxidizers such as chlorates, peroxides, nitrates, etc

Waste Disposal

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill.Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
