A trifluoride can react violently with water, releasing hydrogen fluoride.

The research group synthesized several novel trifluorides and analyzed their crystal structures.

The researchers kept a cylinder of boron trifluoride in the fume hood to use as a Lewis acid catalyst during the synthesis.

The semiconductor factory installed specialized scrubbers to handle nitrogen trifluoride emissions safely.

Researchers wore specialized protective gear when handling chlorine trifluoride in the laboratory.

Because bromine trifluoride is a highly toxic, corrosive liquid soluble in sulfuric acid and used to produce uranium hexafluoride, it is stored under strict safety protocols.

The research team prevented over-fluorination by switching their protocol to diethylaminosulfur trifluoride, a milder reagent for introducing fluorine atoms.
