What is ISODRIN?

Chemical properties

Crystals.

The Uses of ISODRIN

Insecticide.

General Description

Solid. ISODRIN is no longer used as a pesticide. Isomer of aldrin.

Reactivity Profile

ISODRIN is related to aldrin. (nonspecific -- Aldrin) When heated to decomposition ISODRIN emits toxic fumes of chlorine. Unstable, reactions induced by light or acid. [EPA, 1998].

Hazard

Toxic, use may be restricted.

Health Hazard

ISODRIN is classified as extremely toxic. Probable oral lethal dose for humans is 5-50 mg/kg or between 7 drops and 1 teaspoonful for a 70 kg (150 lb.) person. It causes renal damage and hyperactivity of sympathetic nervous system.

Fire Hazard

(Non-Specific -- Aldrin) ISODRIN may burn but may not ignite readily. Container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Material is related to aldrin. (Non-Specific -- Aldrin) When heated to decomposition ISODRIN emits toxic fumes of chlorine. Unstable, reactions induced by light or acid.
