Key Properties
Thorium nitrate pentahydrate (AR) is a radioactive lanthanide-series salt that serves as a reference compound in various analytical and research applications. This compound is notable for its high purity of 99%, making it suitable for precise scientific work. As a member of the actinide series, thorium is of particular interest in nuclear chemistry and materials science. Due to its radioactive nature, the use of thorium nitrate is subject to strict regulatory controls, requiring an end-use certificate for purchase and handling.
Also known as Thorium(IV) Nitrate Pentahydrate.
