A toxic chemical compound containing bromine and nitrogen, similar to the tear gas bromacetone, used historically as a fumigant or pesticide.
From 'bromo-' (containing bromine) + 'picrin' (related to picric acid, an explosive compound). This synthetic chemical was developed in the early 1900s for agricultural and military applications.
Brompicrin was one of the chemical weapons developed during World War I—it's extremely irritating to eyes and lungs. The study of such compounds led to modern chemical safety regulations!
