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.
