Understanding transformation product (TP) formation is crucial for assessing compound fate and environmental risks. TPs are generally more polar and thus more mobile in the aquatic environment than their parent compounds. In addition, the toxicity and persistence of TPs may differ from that of their parents. However, there is often limited information available about TPs, both due to scarce research and inadequate FAIR (Findable, Accessible, Interoperable and Reusable) data on TPs, hindering utilization of and advancement on existing knowledge.
