Chemical Structure

Tetraiodothiophene CAS 19259-11-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 587.73 g/mol gives Tetraiodothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Tetraiodothiophene (CAS 19259-11-1), a certified reference material (molecular formula C4I4S, MW 587.73 g/mol) for analytical method development and quality control.

Based on its molecular formula C4I4S, Tetraiodothiophene contains sulfur-containing functionality, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 587.73 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.

As a certified reference material (CRM), Tetraiodothiophene 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.
