Trichloromethane
Overview
Chloroform (trichloromethane, CHCl3) is a heavy, colorless, volatile liquid. Our Gold Diamond special grade (enterprise standard) reaches 99.95% purity. It is a core feedstock for refrigerant R22 and downstream fluoropolymer materials, and a widely used extraction solvent in pharmaceuticals and fine chemicals.
