Type a chemical name, CAS number or SMILES string. The checker reads the structure and tests it against the three PFAS definitions the laws use: the fully fluorinated carbon wording of Maine, Minnesota and most states, the OECD wording of the EU, and the structural test in the federal TSCA reporting rule. Of the 322 entries in the built-in table, 187 are a PFAS under one definition and not another.
How the three tests work
Fully fluorinated carbon. A class of fluorinated organic chemicals containing at least one fully fluorinated carbon atom. Washington wrote this sentence into its 2018 food packaging law, and most states have used it since. Maine's PFAS rule and a federal statute (15 U.S.C. 8931) define a fully fluorinated carbon atom as one on which all the hydrogen substituents have been replaced by fluorine, and Minnesota's Department of Agriculture applies that test to pesticides. Read that way, CF3 and CF2 groups qualify and so does a single fluorine on an aromatic ring. The checker uses that reading.
OECD CF3 or CF2. Any substance that contains at least one fully fluorinated methyl (CF3) or methylene (CF2) carbon atom without any H, Cl, Br or I attached to it. The EU, Denmark and New Zealand use it. It needs a saturated carbon carrying at least two fluorines, so a lone fluorine on a ring, a CHF2 group or a carbon carrying chlorine beside its fluorines falls outside it.
TSCA structures. EPA's reporting rule (40 CFR 705.3) counts a substance as PFAS if it contains one of three saturated substructures: R-CF2-CF(R')R'', with any R groups; R-CF2-O-CF2-R', where R and R' are fluorine, oxygen or saturated carbon; or CF3-C(CF3)R'R'', where R' and R'' are fluorine or saturated carbon. Single fluorinated carbons, fluorinated aromatic rings and olefins are outside it. New Hampshire's product law adopts this definition by reference.
A yes means the structure contains what the definition describes. It does not mean a law restricts the chemical: each law also limits itself to products, to intentionally added PFAS, and to its own exemptions and named lists. West Virginia's foam law needs two fully fluorinated carbons and excludes polymers, so it gets its own row. Fluoropolymers are tested on a representative repeating unit, refrigerant blends count if any component does, and salts are tested one ion at a time. A one-carbon compound with a double bond, such as carbonyl fluoride, is marked as depending on whether it counts as organic.
Names that are not in the built-in table go from your browser to PubChem, the National Library of Medicine's chemical database, which returns the structure; the tests then run in your browser. The page address includes the name you looked up, and the site's analytics record page addresses if you allow them. See the privacy policy.
The built-in table
322 entries, with structures from PubChem as of October 29, 2026. 94 are PFAS under all three tests. Open a group and pick a name for the reasons.
