Chemical Structure

2,3,4,5-Tetramethylthiophene CAS 14503-51-6 chemical structure

Description

The molecular framework of 2,3,4,5-Tetramethylthiophene (C8H12S) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

CATO supplies 2,3,4,5-Tetramethylthiophene (CAS 14503-51-6), a certified reference material (molecular formula C8H12S, MW 140.25 g/mol) for analytical method development and quality control.

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-Tetramethylthiophene 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.
