You have an API, you’ve discharged it, it passes all specifications, but it’s highly colored so you decide to repeat the crystallization. However, in repeating the crystallization, you this time add activated carbon. The inference is that activated carbon was not part of the original process and the carbon is added to remove the color bodies or impurities. Then the question goes on to ask is this rework or reprocess? The solvent remains the same. If it is a rework, is it a CBE or an annual report?
