WitrynaThe impurity profile depends very much on the manufacturing process; even for the same strain of a micro-organism, impurity profiles may be different. In general, purification steps including column chromatography and ultra-filtration steps may be crucial to achieve a sufficiently pure active substance. WitrynaOxidation reagents play a crucial role in organic synthesis and among the most important is meta-Choroperoxybenzoic acid (mCPBA). Its popularity is due to outstanding reactivity and its ability to reduce the number of reaction steps in classical synthetic routes as well as its relative stability and ease of handling.

mCPBA can be prepared by reacting m-Chlorobenzoyl chloride with a basic solution of hydrogen peroxide, followed by acidification. It is sold commercially as a shelf-stable mixture that is less than 72% mCPBA, with the balance made up of m-chlorobenzoic acid (10%) and water. The peroxyacid can be purified by washing the commercial material with a sodium hydroxide and potassium phosphate solution buffered at …
