Witryna12 sty 2024 · Impurity is defined as any substance coexisting with the original drug, such as starting material or intermediates, that is formed due to any side reactions. The description, characterization, and quantification of the identified and unidentified impurities present in new drug substances are known as impurity profile. 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. read csv data into list python
