Chemical Structure

2,3,4,5-Tetrachlorothiophene CAS 6012-97-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 221.92 g/mol gives 2,3,4,5-Tetrachlorothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,3,4,5-Tetrachlorothiophene (CAS 6012-97-1), a certified reference material (molecular formula C4Cl4S, MW 221.92 g/mol) for analytical method development and quality control.

Structurally, 2,3,4,5-Tetrachlorothiophene (C4Cl4S) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 221.92 g/mol, it falls into the medium-molecular-weight range. 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), 2,3,4,5-Tetrachlorothiophene 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.
