04 · Handling and storage
Storing and handling 3-Aminophenol
Storage conditions
Store in tightly closed containers in a cool, well-ventilated area. Aminophenols must be stored to avoid contact with strong oxidizers (such as chlorine, bromine, and fluorine), since violent reactions occur. /Aminophenols/
