It is also a precursor to various refrigerants. B) Chloroform did not induce unscheduled DNA synthesis in vitro or in vivo in mice (Larson et al, 1994). Phosgene reacts with water to form carbon dioxide and HCl,[63] and the carbonate salt neutralizes the resulting acid. For more information, call the ATSDR Information Center at 1-888-422-8737.
