Another important feature of the workflow is the ability to trace relevant analogue reactions that were removed for a certain reason. For instance, Scheme 3 shows the analogue reaction (Reaxys® ID 192530) leading to a similar ethylated impurity with a higher relevance score of 0.76 compared to the analogue reaction after condition filtering shown in Figure which has a relevance of 0.73. Despite this, the reaction was removed due to a missing temperature record.
