Chemical Structure
Description
5,5'-Dibromo-3,3'-dihexyl-2,2'-bithiophene (C20H28Br2S2) contains sulfur-containing functionality, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5,5'-Dibromo-3,3'-dihexyl-2,2'-bithiophene (CAS 170702-05-3) is a high-purity analytical reference standard with the molecular formula C20H28Br2S2 and a molecular weight of 492.37 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
