Biochem/physiol Actions

Thimerosal is a sulfhydryl (thiol) oxidizing reagent capable of inhibiting a wide range of sulfhydryl-dependent enzymes and proteins such as PI3-kinase-dependent methionine synthase, glutamate transport receptors, and Na++K+ dependent ATPases.

Features and Benefits

  • Meets USP/EP testing specifications
  • High-quality chemical, suitable for a wide variety of research applications.

Other Notes

As part of the corporation global plan to support the Minamata Convention eliminating mercury-containing compounds, as of January 2021 customers will be required to provide an End-Use Declaration. The sales of thimerosal will be restricted for approved applications only, such as preservative in vaccine manufacturing, preservative in eye cosmetics, research use within academia (excluding preservation intent) and as reference material only. The product is not intended for use as a biocide under global biocide regulations, including but not limited to US EPA′s Federal Insecticide Fungicide and Rodenticide Act , European Biocidal Products Regulation, Canada’s Pest Management Regulatory Agency, Turkey’s Biocidal Products Regulation, Korea’s Consumer Chemical Products and Biocide Safety Management Act (K-BPR) and others.
