Chemical Structure
Description
The occurrence of 3,4-Dibromoselenophene is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,4-Dibromoselenophene (CAS 17422-59-2) is a high-purity analytical reference standard with the molecular formula C4H2Br2Se and a molecular weight of 288.83 g/mol.
Based on its molecular formula C4H2Br2Se, 3,4-Dibromoselenophene contains bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), 3,4-Dibromoselenophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
