Tri-Hydrox-Dioxide

Background
Hydrox-Dioxide was used by several pre-War companies in treating animal wastes and was outlawed by the Environmental Protection Agency in 2066. The chemical was used in recycling certain nutrients and extracting moisture from raw sewage, but it required careful storage measures and was both toxic and flammable. If inhaled, it can cause extreme nausea, and if you have the misfortune of being exposed to a large dose, it can be lethal.
