Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.14 g/mol gives 2-Bromo-5-butylThiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Bromo-5-butylThiophene (CAS 128619-83-0), molecular formula C8H11BrS and molecular weight 219.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromo-5-butylThiophene (C8H11BrS) contains sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-Bromo-5-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.
