Description: List of all registered DSSTox Per- and Polyfluoroalkyl Substances (PFAS) created using ChemAxon’s Markush structure-based query representations. Markush structures can be broad and represent typical PFAS categories or they can represent mixtures or polymers containing ambiguous or generalized structural elements (s.a., unknown location of substituent, or variable chain length). Each PFAS Markush registered with a unique DTXSID is considered a generalized substance or “parent ID” that can be associated with one or many “child IDs” (i.e., many parent-child mappings) within the full DSSTox database. These mixture or category DTXSIDs can be used to search and retrieve all currently registered DSSTox substances within the group, and offer an objective, transparent and reproducible structure-based means of defining a generalized set of chemicals. This list encompasses the content of another registered list (EPAPFASCAT), the latter containing only the subset representing category mappings.
