Hydrogen fluoride is a chemical compound with the chemical formula HF. This colorless gas or liquid is the principal industrial source of fluorine often as an aqueous solution called hydrofluoric acid. It thus is the precursor to many important compounds including pharmaceuticals and polymers (e.g. Teflon). HF is widely used in the petrochemical industry as a component of superacids. Hydrogen fluoride boils near room temperature much higher than other hydrogen halides. Unlike other hydrogen halides HF is lighter than air.
