Fluoroacetamide

Fluoroacetamide	Last updated: 17/01/2023
(Also known as: monofluoroacetamide)

SUMMARY

Fluoroacetamide is a insecticide and rodenticide. It is highly soluble in water and highly volatile. It is highly toxic to mammals and has a high potential for bio-concentration. It is a neurotoxin and may cause adverse reproduction/development effects. Fluoroacetamide is highly toxic to bids and moderately toxic to fish.
