Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 288.93 g/mol gives 3-Bromo-4-iodothiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Bromo-4-iodothiophene (CAS 73882-41-4), molecular formula C4H2BrIS and molecular weight 288.93 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Bromo-4-iodothiophene (C4H2BrIS) is characterized by sulfur-containing functionality, bromine/iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 3-Bromo-4-iodothiophene 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.
