Product Introduction
Chloroform is a dense, colorless, volatile liquid with a sweet, ethereal odor. Historically used as an anesthetic, it’s now mostly employed as a solvent, an intermediate in refrigerant (HCFC‑22) and PTFE production, for lipid extraction, and as an NMR standard (deuterated CDCl₃).
