Glucin

Glucin is an artificial sweetening agent similar to saccharin that was used in the early 20th century.

It is composed of a mixture of mono- and di-sulfonic acids with a chemical formula of C19H16N4.

[2] It typically appears as a light brown powder, easily soluble in water.

Glucin is about three hundred times sweeter than cane sugar.

[2] The use of glucin as a food additive is prohibited in much of the United States due to concerns about its health effects.
