This compound group was populated by a substructure search in PubChem using the SMILES string for PFHS (perfluorohexanesulfonate), replacing terminal CF3 with CF2 to allow for longer chain lengths:

C(C(C(C(F)(F)S(=O)(=O)[O-])(F)F)(F)F)(C(C(F)F)(F)F)(F)F

This compound group was populated by a substructure search in PubChem using the SMILES string for PFOA, but replacing the terminal CF3 with CF2 to allow for longer chains:

C(=O)(C(C(C(C(C(C(C(F)F)(F)F)(F)F)(F)F)(F)F)(F)F)(F)F)O

Esters and ethers were manually removed.

MAK provides the following criteria for the organic mercury compounds it flags as hazardous. This compound group is defined by the SMILES/SMARTS string "C[Hg]" and populated from a substructure search of PubChem.

"Organomercury compounds are characterized chemically by the covalent binding of one or two alkyl or aryl groups and covalent or ionic binding of a group such as halide,hydroxide, acetate, nitrate or phosphate to the mercury atom."
