Except where noted otherwise, data are given for materials in their standard state (at 25 °C, 100 kPa)Infobox references Microcosmic salt (see infobox for other names) is a salt found in urine with the formula (NH4)NaHPO4. In the mineral form, microcosmic salt is called stercorite.
The first extraction of pure phosphorus came from this salt, when Hennig Brandt attempted to extract gold from urine.
Microcosmic salt is used in the laboratory as an essential ingredient of the microcosmic salt bead test for identification of metallic radicles on the basis of the color they produce in oxidising or reducing flame, in hot or cold condition.
Microcosmic salts form a tetrahydrate.
