Chemical Structure
Description
As a certified reference material (CRM), 2-bromo-3-(methylsulfanyl)thiophene 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.
CATO supplies 2-bromo-3-(methylsulfanyl)thiophene (CAS 94781-39-2), a certified reference material (molecular formula C5H5BrS2, MW 209.13 g/mol) for analytical method development and quality control.
The molecular framework of 2-bromo-3-(methylsulfanyl)thiophene (C5H5BrS2) is characterized by sulfur-containing functionality, bromine substitution. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
