We have calculated Thresholds of Toxicological Concern (TTC) for a 45,000-chemical universe defined previously Mansouri et al 2016. We used Toxtree v3.1.0 to determine the TTC class and the Kroes Decision for each compound. Sort and filter the table to interact with the data, or search for a compound of interest by entering its name into the search bar.
