CAS 7783-00-8: Selenious acid

Selenous acid (99.999%-Se) PURATREM

Selenous acid is used in steel guns, wherein it changes the color of the steel from silver-grey to blue-grey. It serves as an important component of the Mecke reagent, which is utilized for drug testing. It acts as a source of selenium. It acts as a reagent for alkaloids and an oxidizing agent. Further, it is used in labeling radiopharmaceuticals. It is involved in the organic synthesis for the preparation of glyoxal. 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.

Selenious acid is a white, odorless crystalline solid that is soluble in water. It has been used as a fixative agent in biological and biochemical studies. Selenium inhibits the activity of cyclin D2, nitrate reductase, and methyltransferases. Selenious acid also has inhibitory properties against human lung cells (HL-60). The rate constant for the reaction with selenite was determined to be 1.8 x 10^(-4) M-1 s-1 at 25 degrees Celsius, which is much higher than that of other metal ions tested. Selenious acid can be detected by chromatographic analysis and can be quantified by measuring the hydrogen selenide released during the reaction between it and water vapor.
