Usage

Chemical Properties

Liquid. Miscible with water.

Uses

Insecticide.

General Description

Colorless liquid. Used as a systemic aphicide in Europe, insecticide. Currently of little commercial interest. Not registered as a pesticide in the U.S.

Reactivity Profile

Isolan powder(content2%-20%) 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.

Hazard

Cholinesterase inhibitor.

Health Hazard

Different sources of media describe the Health Hazard of 119-38-0 differently. You can refer to the following data:
1. Isolan powder(content2%-20%) is classified as extremely toxic. Probable oral lethal dose in humans is 5-50 mg/kg or between 7 drops and 1 teaspoonful for a 150-lb. person. A cholinesterase inhibitor; although it is not an organic phosphate, it resembles that group in action.
2. Extremely toxic carbamate; exhibits acute,delayed and chronic effects similar toorganophosphates; cholinesterase inhibitor;found to be more toxic to rats bydermal than oral route (Merck 1996); toxicsymptoms include trembling, pinpoint pupils,lacrimation, excessive salivation, sweating,slurring of speech, jerky movements, nausea,vomiting, loss of bladder control, slightblueness of skin, lips, and nail beds, aswell as convulsion, and coma (Gosselin et al.1984); death can occur from respiratoryarrest; oral lethal dose in adult humanestimated to be within the range 0.5–2 g.LD50 oral (rat): 11 mg/kgLD50 skin (rat): 5.6 mg/kg.

Fire Hazard

When heated to decomposition, Isolan powder(content2%-20%) emits toxic fumes of nitrogen oxides.

Safety Profile

Poison by ingestion, skin contact, and intraperitoneal routes. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. An insecticide. When heated to decomposition it emits toxic fumes of NOx. See also CARBAMATES
