Hi Jeffrey:
The chemistry of osmium tetroxide is well known, and used for dihydroxylation of alkenes and other reactions. A plethora of literature is available on osmium tetroxide chemistry. I will be more worried about its toxicity than its oxidizing
properties during any manipulation.
Osmium tetroxide is very toxic and has an OSHA
permissible exposure limit (PEL) of 0.002 mg/m3.

Subject: [DCHAS-L] Osmium Tetroxide
Hello
I’m currently working on Chemical SOPs.
While working on Osmium Tetroxide I’ve been looking at other SOP’s from other Colleges/Universities and many say it is a strong oxidizer. Which makes sense but when you look at the SDS sheets and in particular the GHS for this chemical;
oxidizer isn’t listed as a hazard. I’m looking at it in a solution and by itself (100%) and still no oxidizer warning.
Any guidance would be greatly appreciated.
Thanks
