CAS 20816-12-0: Tetraossido di osmio

Descrizione: Tetraossido di osmio (OsO4) è un composto altamente reattivo e volatile noto per le sue forti proprietà ossidanti. Si presenta come un solido o liquido incolore o giallo pallido, a seconda del suo stato, e ha un odore distintivo e pungente. Tetraossido di osmio è solubile in solventi organici come l'acetone e l'alcol, ma solo leggermente solubile in acqua. È utilizzato principalmente in chimica organica come reagente per l'ossidazione degli alcheni per formare dioli, e gioca un ruolo cruciale nella microscopia elettronica come fissativo grazie alla sua capacità di legarsi a lipidi e proteine. Tuttavia, è anche altamente tossico e presenta rischi significativi per la salute, inclusi irritazione respiratoria e cutanea, e potenziali effetti cancerogeni. Pertanto, la manipolazione di Tetraossido di osmio richiede rigorose precauzioni di sicurezza, inclusi l'uso di cappe aspiranti e dispositivi di protezione individuale. Le sue proprietà uniche lo rendono prezioso in varie applicazioni scientifiche, ma i suoi pericoli richiedono una gestione attenta negli ambienti di laboratorio.
