Péligot proved that the black powder of Martin Heinrich Klaproth was not a pure metal (it was an oxide of uranium, known in chemistry as UO₂). He then succeeded in producing pure uranium metal by reducing uranous chloride (UCl₄) with potassium metal^[2]. Today better methods have been found^[3].

Peligot's salt is also named after him.

Péligot was professor of analytical chemistry at the Institut national agronomique. He collaborated with Jean-Baptiste Dumas. Together, they discovered the methyl radical during experiments on wood spirit (methanol). The terminology "methlic alcohol" was created by both chemists from "wood wine". They also prepared the gazeous dimethyl ether, and many esters. In 1838, the succeed in transformation camphor into p-cymène using phosphorus pentoxide.
