Trichloroethylene (TCE)
CAS Number: 79-01-6
Trichloroethylene (TCE, ≥99.5%) is a chlorinated solvent traditionally used for vapor-phase metal degreasing, cleaning of precision engineering parts, and as an intermediate for HFC-134a refrigerant production. Its exceptional solvency for greases, oils, and waxes makes it highly effective in critical cleaning applications, though use is regulated in many regions.
