Description

Oxidation, catalyst in Sharpless dihydroxylations Osmium(VIII) oxide is used in the Sharpless oxyamination to give vicinal amino-alcohols. It is used to oxidize alkenes to the vicinal diols. It acts as a staining agent used in transmission electron microscopy to provide contrast to the image and as a stain for lipids in optical microscopy. As a polymer stain, it is also used to stain selectively copolymers especially styrene-butadiene block copolymers. Further, it is involved in the synthesis of Isosteviol. 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.
