Description

General description: Sodium metabisulfite (MBS, Sodium disulfite) is an inorganic salt. It is the sodium salt of disulphurous (pyrosulfurous) acid. It is widely used as reducing agent in textile and photography industry.[1] It is commonly added to various foods and wines as preservative.[2]
Application: Sodium metabisulfite was used to initiate the cross-linking of polybutadiene in the cores of the vesicle membranes by free radical polymerization in solution.[3] It has been used to prevent the oxidation (as antioxidant) during the preparation of stock solutions of 6-hydroxydopamine in various studies.[4][5]
