DIMETILAN Chemical Properties,Usage,Production

Description

Dimetilan is a yellow to reddish-brown solid.Molecular weight= 240.30; Freezing/Melting point =6871℃ (the technical grade at 5565℃). HazardIdentification (based on NFPA-704 M Rating System):Health 3, Flammability 1, Reactivity 1. Soluble in water;solubility 5 24% at 25℃.

Uses

Insecticide.

Uses

Dimetilan is a compound once used in insecticides.

General Description

Colorless solid. The technical product is a yellow to reddish-brown solid. Used as an insecticide for insect control on livestock, especially housefly control. DIMETILAN is no longer produced commercially in the U.S.

Air & Water Reactions

Readily soluble in water [Farm Chemicals Handbook].

Reactivity Profile

DIMETILAN is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Health Hazard

Very toxic; probable oral lethal dose for humans is 50-500 mg/kg or between 1 teaspoon and 1 oz. for a 70 kg (150 lb.) person. DIMETILAN is highly toxic by ingestion and moderately toxic by contact with the skin. Death is primarily due to respiratory arrest of central origin, paralysis of the respiratory muscles, intense bronchoconstriction, or all three. DIMETILAN is a cholinesterase inhibitor.

Fire Hazard

When heated to decomposition, DIMETILAN emits toxic fumes of nitrogen oxides. (Non-Specific -- Carbamate Pesticide, Solid, n.o.s.) DIMETILAN may burn but does not ignite readily. Container may explode in heat of fire. Hydrolyzed by acids and alkalis.

Agricultural Uses

Insecticide: An insecticide formerly used for insect control on livestock, especially housefly control. Not registered for use in the U.S. or in EU countries. There are 10 global suppliers.

Trade name

Potential Exposure

Formerly an insecticide for insect control on livestock, especially housefly control. It is no longerproduced commercially in the United States.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Speed in removing material from skinis of extreme importance. Shampoo hair promptly if contaminated. Seek medical attention immediately. If thischemical has been inhaled, remove from exposure, beginrescue breathing (using universal precautions, includingresuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit. Speedin removing material from skin is of extreme importance.Remove and isolate contaminated clothing and shoes at thesite. Keep victim quiet and maintain normal body temperature. Effects may be delayed; keep victim underobservation

storage

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, wellventilated area.

Shipping

Carbamate pesticides, solid, toxic, n.o.s. requirea “POISONOUS/TOXIC MATERIALS” label. They are inHazard Class 6.1 and dimetilan is in Packing Group II.
