Suosan is calorie-free artificial sweetener derived from β-alanine, discovered in 1948 by Petersen et Muller.[1]
Suosan is a sodium salt of p-Nitrophenylcarbamidopropionic acid and is 700 times sweeter than sucrose (table sugar)[2] with a bitter aftertaste.[3] It was never commercialized due to its low solubility in water, particularly under acidic pH (which limited its use, particularly in soft drinks)[4][5] and concerns that it might form the toxic compound 4-nitroaniline.[5]
