What is Tiopronin?
It is a white to off-white powder with its characteristic odor.
Of course, as an organic sulfur compound, it doesn’t smell good, at least not pleasant.
Tiopronin is soluble in water or ethanol, and very slightly soluble in chloroform or ether.
Meanwhile, as a reducing molecule, tiopronin quickly goes bad when exposed to high temperatures and sunlight.
