  • Little is known about the properties of endrin aldehyde, an impurity and breakdown product of endrin, or endrin ketone, which is a product of endrin when it is exposed to light. (cdc.gov)
  • Endrin may also be broken down by exposure to high temperatures (230�C) or light to form primarily endrin ketone and endrin aldehyde. (cdc.gov)
  • derivatives
