METHANESELENINIC ACID Chemical Properties,Usage,Production

Uses

Methaneseleninic acid may be employed as a ligand in the preparation of lanthanide complexes. It may also be used in the synthesis of a 12-membered macrocycle [(p-MeO-C₆H₄)₂Te(μ-O)-(μ-MeSeO₂)(μ₄-Cl)]₂ by reacting with bis(p-methoxyphenyl)tellurium dichloride.

Definition

ChEBI: An organoselenium compound that is seleninic acid in which the hydrogen attached to selenium is replaced by a methyl group.

General Description

Methaneseleninic acid is an oxidizing agent useful in organic synthesis. It is formed as major product during the oxidations of γ-glutamyl-Se-methylselenocysteine and Se-methylselenocysteine.
