Hassium tetroxide (also hassium(VIII) oxide) is the inorganic compound with the formula HsO4. It is the highest oxide of hassium, a transactinide transition metal. It has little use outside of scientific interest, where it is often studied in comparison to osmium tetroxide and ruthenium tetroxide, its lighter octavalent group 8 element analogs.
