Sodium orotate, NaC5H3N2O4, is the sodium salt of orotic acid, a metabolic intermediate and chelating agent for certain cations. It is of particular interest as a salt of sodium with a very low solubility in water.

Availability and Preparation

While sodium orotate is not generally available itself, other salts of orotic acid are available as nutritional supplements, particularly magnesium orotate. With the exception of the equally insoluble potassium orotate, these salts will react with sodium chloride in water to precipitate sodium orotate.

Handling, storage and disposal

Sodium orotate is generally inert and not expected to pose environmental hazards in reasonable quantities, although the low solubility and high sodium content mean that it should not flow down a drain or be allowed to mix with soil.
