Chloroform radical
WebMETHYL chloroform (111 trichloro ethane) was introduced into general use in 1955–60 in response to the need for a general solvent which was less toxic than those then in use. Its ubiquitous presence in the northern and southern hemispheres, first reported in 1974 (ref. 1), has since been confirmed2,3. WebChloroform is unstable and is combined with a variety of stabilizers to enhance product shelf life. We offers ethanol and amylene stabilized chloroform. Like ether, …
