Description

clear colorless to yellowish viscous solution Monothioglycerol occurs as a colorless or pale-yellow colored, viscous, hygroscopic liquid with a slight odor of sulfide.

Liquid

Monothioglycerol is a thiol that is glycerol in which one of the primary hydroxy groups is replaced by a thiol group. It has a role as a vulnerary and a reducing agent. It is a thiol and a member of propane-1,2-diols.
