Synonyms for the chemical compound Sodium Ethylmercurithiosalicylate are not commonly used and may be difficult to find. However, there are similar compounds that have been used for similar purposes in the past. One such compound is Thiomersal, which is also known as sodium ethylmercury thiosalicylate. Thiomersal was a popular preservative used in vaccines and other medical products but has been largely phased out due to safety concerns. Another similar compound is Merthiolate, which is also known as thimerosal and has been used as an antiseptic and antifungal agent. However, like Thiomersal, Merthiolate has also been scrutinized for its potential adverse effects.
