Sodium periodate

Sodium periodate (CAS 7790-28-5, EC 232-197-6, formula HIO4.Na) is an inorganic iodine-based oxidising salt, also referred to as sodium metaperiodate or sodium m-periodate. It carries no assigned E-code and is commercially available as a white crystalline powder.

In pharmaceutical manufacturing, sodium periodate cleaves vicinal diol groups in carbohydrates and glycoproteins, enabling controlled conjugation reactions in drug synthesis and bioassay preparation. In water treatment and textile processing, it acts as a biocide and bleaching agent by releasing reactive oxygen species that degrade organic contaminants and disrupt microbial cell function.

Sodium periodate is supplied in technical and reagent grades, with material conforming to REACH registration requirements for the European market. Packaging typically ranges from laboratory-scale quantities to bulk industrial formats. Buyers should confirm grade specification against application requirements, particularly where pharmaceutical or analytical use is intended.
