Thimerosal

August 8, 2011

Thimerosal is the generic name for a mercury-based topical antiseptic and antifungal agent that came to be far better known by the Eli Lilly trade name Merthiolate. Outside the United States, its generic name is thiomersal. It has also been used as a vaccine preservative, but this use is being phased out in many countries. M. S. Kharasch at the University of Maryland patented thimerosal and similar compounds in 1928.
