Description
Compared with other compounds in its class, the molecular weight of 209.13 g/mol gives 4-Bromo-2-(methylthio)thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Bromo-2-(methylthio)thiophene (CAS 87310-65-4), molecular formula C5H5BrS2 and molecular weight 209.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2-(methylthio)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. 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 4-Bromo-2-(methylthio)thiophene 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.
