CAS 54-64-8

Thimerosal

Description:

Thimerosal, with the CAS number 54-64-8, is an organomercury compound that has been widely used as a preservative in vaccines and other pharmaceutical products. It appears as a colorless to pale yellow liquid and is soluble in water and alcohol. Thimerosal contains approximately 49% mercury by weight, which is a key characteristic that has raised concerns regarding its safety and potential toxicity. The compound acts as an antimicrobial agent, preventing the growth of bacteria and fungi in multi-dose vaccine vials. However, due to its mercury content, its use has been reduced or eliminated in many vaccines, particularly in pediatric formulations, amid public health discussions about mercury exposure. Thimerosal is metabolized in the body to ethylmercury, which is excreted more rapidly than methylmercury, another form of mercury that is more toxic and accumulates in the body. Regulatory agencies, including the World Health Organization and the U.S. Centers for Disease Control and Prevention, have evaluated its safety, concluding that thimerosal in vaccines poses minimal risk to human health.

Thiomersal

Controlled Product

CAS: 54-64-8

Thiomersal is a preservative that is used in vaccines and other pharmaceutical products. It has been shown to have biochemical properties that are similar to those of benzalkonium chloride, which may cause cross-reactivity with the sephadex G-100 gel. Thiomersal has been shown to have an adverse effect on the polymerase chain reaction (PCR) by inhibiting the activity of DNA polymerases. Thiomersal also inhibits certain enzymes activities, such as cytosolic Ca2+-ATPase, and can affect human serum proteins and water vapor.
