CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Endrin is a white crystalline, odorless solid dissolved in a liquid carrier. It is water emulsifiable. It is toxic by inhalation, skin absorption, and/or ingestion. When heated or burned it may emit toxic hydrogen chloride and phosgene. It is used as a pesticide. |

PRODUCT INTRODUCTION
description
Endrin is a solid, white, almost odorless substance that was used as a pesticide to control insects, rodents, and birds. Endrin has not been produced or sold for general use in the United States since 1986. Little is known about the properties of endrin aldehyde (an impurity and breakdown product of endrin) or endrin ketone (a product of endrin when it is exposed to light).
