PICRIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Picric acid, also known as 2,4,6-trinitrophenol, is a yellow crystalline solid with the chemical formula C6H3N3O7. It is highly explosive and was historically used in military munitions. Today, its primary uses include laboratory reagent, chemical synthesis, and as a dye in the textile industry. Picric acid is highly toxic and can cause severe skin and eye irritation, respiratory issues, and systemic poisoning if ingested. Handling requires strict safety measures, including the use of protective gloves, goggles, and face shields. It should be stored in a cool, dry place, away from heat, shock, and friction sources. Picric acid must be kept moist to reduce its explosive risk. Disposal should follow local hazardous waste regulations to prevent environmental contamination. Despite its dangers, picric acid remains a valuable chemical in specific industrial and scientific applications.
