Compound Groups

This compound group is populated with ChemForward's inadvertent PCB (iPCB) Pigment Resources - pigments with "Yes" for "Contains Chlorine?" or a "Yes" for "Manufactured using chlorine solvent?".

C2C v4

This compound group is populated from EPAPFASIV's list. EPA filtered several publicly available PFAS lists to exclude most high (>500) and low (<50) molecular weight compounds, aromatic compounds, metal-containing compounds, and chemicals with a low ratio of fluorine to carbon. The PFAS chemicals in this list are in the current inventory found to be soluble in DMSO.

This compound group is populated by selecting halogenated solvents (excluding salts) from GSPI's Six Classes of Problematic Chemicals - Some Solvents List.

This compound group is populated from "A Class Approach to Hazard Assessment of Organohalogen Flame Retardants" by National Academies of Sciences, Engineering, and Medicine. The committee identified a set of 1073 analogue compounds as "expanded set" based on combined functional, structural, and predicted bioactivity information.

The subclasses from the seed list used to expand this list are also in Pharos:

• Polyhalogenated alicycles (NAS OFR subclass)
• Polyhalogenated aliphatic carboxylate (NAS OFR subclass)
• Polyhalogenated aliphatic chains (NAS OFR subclass)
• Polyhalogenated benzene alicycles (NAS OFR subclass)
• Polyhalogenated benzene aliphatics and functionalized (NAS OFR subclass)
• Polyhalogenated benzenes (NAS OFR subclass)
• Polyhalogenated bisphenol aliphatics and functionalized (NAS OFR subclass)
• Polyhalogenated carbocycles (NAS OFR subclass)
• Polyhalogenated diphenyl ethers (NAS OFR subclass)
• Polyhalogenated organophosphates (NAS OFR subclass)
• Polyhalogenated phenol derivatives (NAS OFR subclass)
• Polyhalogenated phenol-aliphatic ethers (NAS OFR subclass)
• Polyhalogenated phthalates/benzoates/imides (NAS OFR subclass)
• Polyhalogenated triazines (NAS OFR subclass)

“Methoxychlor” refers to any possible isomer of dimethoxydiphenyltrichloroethane or any combination thereof.

This compound group contains designated chemicals identified by Biomonitoring California that are organophosphorous pesticides, metabolites of organophosphorous pesticides, and other targets for measurement in biomonitoring studies.  Designated chemicals are are the list of chemicals from which Biomonitoring California's Scientific Guidance Panel recommends priority chemicals for biomonitoring. The most current list of designated chemicals may be found at https://www.biomonitoring.ca.gov/chemicals/designated-chemicals.

This compound group is compiled from WA DoE for Toxic-Free Cosmetics Act. Members CAS are subject to changes as rulemaking finalizes.

The substances included in the group cover linear and branched aliphatic and aromatic siloxanes as well as cyclic siloxanes. In addition polymeric siloxanes notified under previous legislation (NONS) have been included in the group.

This compound group was populated from the 2016 GADSL list at http://www.gadsl.org/
