Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.14 g/mol gives 2-Bromo-5-tert-butylthiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-5-tert-butylthiophene (CAS 93425-02-6), molecular formula C8H11BrS and molecular weight 219.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-5-tert-butylthiophene (C8H11BrS) 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.
CATO manufactures 2-Bromo-5-tert-butylthiophene 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.
