D-Mannitol, Powder, USP, EP, Injectable grade is a diuretic used to increase urine production. D-Mannitol is also known as mannite or manna sugar. It is used to relieve osmotic stress in plants and used clinically in osmotherapy. It is classified as a sugar alcohol and is most commonly observed in its white crystalline solid form. It has several uses, ranging from inducing osmotic stress in plants to being used to produce tablets of medicine. It can also be added to boric acid to increase the strength of the acid in order to allow for a better degree of accuracy in volumetric analysis of the acid.
