Products under the name ligroin can have boiling ranges as low as 60‒80 ℃ and may be practically indistinguishable from a petroleum ether with the same boiling range.

Ligroin is assigned the CAS Registry Number 8032-32-4, which is also applied to many other products, particularly the lower boiling ones, called , petroleum ether, and petroleum benzine.
