CAS 123334-20-3: Vanadyl sulfate hydrate

Vanadium(IV) sulfate oxide hydrate

Vanadium(IV) sulfate oxide hydrate is used as a catalyst for the oxidative aromatization of cyclohexenone. It is also used as a component in some food supplements. It is one of the intermediate during the extraction of vanadium from petroleum residues. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Vanadium oxide hydrate is an oxidizing catalyst that is used in the production of polyvinyl chloride (PVC). It is also used as a catalyst in the oxidation of water vapor and in the preparation of hydroxide solutions. The catalytic activity of vanadium oxide hydrate depends on its pH, with a lower pH increasing the rate of oxidation. This compound was shown to induce DNA strand breaks and chromosomal aberrations when tested in vitro. Vanadium oxide hydrate has also been found to have genotoxic effects when tested in vivo, including induction of micronuclei and sister chromatid exchanges. Vanadium oxide hydrate can be used as a dietary supplement to increase growth factor levels, particularly when combined with molybdenum or monoclonal antibody. Vanadium oxide hydrate has a phase transition temperature at around 74°C, which makes it useful for regulating polymer film thickness during processing.
