Usage

Uses

Different sources of media describe the Uses of 644-64-4 differently. You can refer to the following data:
1. Insecticide.
2. 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.
