CAS 7791-23-3

Selenium oxychloride

Description:

Selenium oxychloride, with the CAS number 7791-23-3, is an inorganic compound characterized by its unique combination of selenium, oxygen, and chlorine. It typically appears as a colorless to yellowish liquid and is known for its hygroscopic nature, meaning it can absorb moisture from the air. This compound is primarily used in organic synthesis and as a reagent in various chemical reactions. Selenium oxychloride is notable for its ability to act as both an oxidizing agent and a chlorinating agent, making it valuable in the preparation of selenium-containing compounds. It has a relatively low boiling point and can be volatile under certain conditions. Due to its chemical reactivity, it must be handled with care, as it can be corrosive and toxic, posing health risks upon exposure. Proper safety measures, including the use of personal protective equipment and adequate ventilation, are essential when working with this substance in a laboratory setting.

Seleninyl chloride

Controlled Product

CAS: 7791-23-3

Seleninyl chloride is a chemical compound that contains a selenium atom and chloride ion. The compound is used to synthesize organic compounds containing the selenium-carbon bond, such as cyclin D2. Seleninyl chloride reacts with hydrochloric acid to produce selenium dioxide, which has been shown to have immunomodulatory effects. Magnetic resonance spectroscopy (MRS) has been used to identify the structural analysis of the reaction products of this compound. MRS can also be used to observe low-energy magnetic fields in water vapor and measure thermal expansion during reactions. Seleninyl chloride is not a reactive intermediate, but it does undergo a reaction with water vapor at high temperatures.
