Osmic Acid

2,100.00

Osmic acid was first used by von Reis and Swensson in 1951 for the treatment of knee effusion [1]. It is an aqueous solution of osmium tetroxide, which is a vigorous oxidizing agent that has a high affinity for lipids and coagulates proteins. It is deposited in inflamed synovial tissue and subsynovial fat.

INFORMATION OF OSMIC ACID
Osmium tetroxide (also osmium(VIII) oxide) is the chemical compound with the formula OsO4. The compound is noteworthy for its many uses, despite the rarity of osmium. It also has a number of interesting properties, one being that the solid is volatile. The compound is colourless, but most samples appear yellow.[5] This is most likely due to the presence of the impurity OsO2, which is yellow-brown in colour.

USES OF OSMIC ACIDn organic synthesis OsO4 is widely used to oxidise alkenes to the vicinal diols, adding two hydroxyl groups at the same side (syn addition). See reaction and mechanism above. This reaction has been made both catalytic (Upjohn dihydroxylation) and asymmetric (Sharpless asymmetric dihydroxylation).
