Para-Chlorobenzotrifluoride (PCBTF)

  • Aromatic solvents
  • CAS 98-56-6
  • IUPAC: 1-Chloro-4-(trifluoromethyl)benzene

Para-Chlorobenzotrifluoride (PCBTF) (CAS 98-56-6) appears in 5 of the 1,812 car-care products CarCareTruth tracks (as of June 2026).

EPA-exempt VOC (not photochemically reactive), making it attractive for CARB-compliant formulations. PCBTF is a suspected reproductive toxicant in animal studies and is aquatically toxic with low LC50 values. Inhalation of vapors should be avoided; use with ventilation. Not Prop 65 listed.

Para-chlorobenzotrifluoride (PCBTF) is an aromatic solvent used in paints, coatings, and car care products primarily because it is EPA-exempt from VOC regulations (it reacts slowly in the atmosphere and doesn't contribute to smog). This makes it popular in CARB-compliant formulations.

Despite its VOC-exempt status, PCBTF is not without hazard: it has documented aquatic toxicity and limited biodegradability, and animal studies have raised reproductive concerns. Its use in car care products is typically at low concentrations in products like sealants and coatings where a high-solvency, low-evaporation carrier is needed.

The environmental profile is poor relative to more benign solvents — persistent, not biodegradable, and aquatically toxic.
