General Description

Phosphorus trifluoride, denoted by the chemical formula PF3, is a colorless and odorless gas. As a polar compound with trigonal pyramidal geometry, it is composed of one phosphorus atom and three fluorine atoms. It is known for its reactivity and ability to form coordination compounds with transition metals. Phosphorus trifluoride is also notable for its toxicity and potentially damaging effects on the respiratory system and eyes. It is primarily used in the semiconductor industry and is typically stored and transported in pressurized cylinders.
