Chemical Structure

Thimerosal CAS 54-64-8 chemical structure

Description

As a certified reference material (CRM), Thimerosal meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Thimerosal (CAS 54-64-8) is a high-purity analytical reference standard with the molecular formula C9H9HgO2SNa and a molecular weight of 404.81 g/mol.

Based on its molecular formula C9H9HgO2SNa, Thimerosal contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 404.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
