- Make difluoroacetate salts
Difluoroacetic acid is toxic, though less so than its monofluoroacetic derivate. Chronic exposure has been linked to nerve and liver damage.
In closed bottles, with a PTFE seal and a hazardous chemical label.
Should be neutralized with a base. The resulting salts should be taken to waste disposal facilities or recycled.
