Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 191.09 g/mol gives 2-Bromo-3,4-dimethylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Bromo-3,4-dimethylthiophene (CAS 169328-87-4), a certified reference material (molecular formula C6H7BrS, MW 191.09 g/mol) for analytical method development and quality control.
The molecular framework of 2-Bromo-3,4-dimethylthiophene (C6H7BrS) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 2-Bromo-3,4-dimethylthiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
