CAS 7783-00-8: Ácido selenioso

Descripción:
Ácido selenioso, con la fórmula química H2SeO3, es un selenoácido que contiene selenio en su estado de oxidación +4. Es un líquido incoloro e inodoro que es altamente soluble en agua, formando una solución débilmente ácida. Ácido selenioso es conocido por su capacidad para actuar como agente reductor y puede participar en varias reacciones químicas, incluidos los procesos de oxidación-reducción. Se produce típicamente por la oxidación de selenio o selenuros. El compuesto exhibe propiedades similares al ácido sulfuroso, ya que ambos son oxoácidos de calcógenos. Ácido selenioso se utiliza en química analítica y puede servir como precursor para la síntesis de otros compuestos de selenio. Sin embargo, es importante manejarlo con cuidado, ya que es tóxico y puede representar riesgos para la salud al exponerse. Se deben tomar las medidas de seguridad adecuadas al trabajar con esta sustancia, incluyendo el uso de equipo de protección personal y trabajar en un área bien ventilada.

  • Selenious acid

    CAS:
    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.
    Pureza:Min. 95%
