Chemical Structure
Description
As a certified reference material (CRM), (2-Bromoethyl)(phenyl)selane 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.
(2-Bromoethyl)(phenyl)selane (CAS 50630-23-4) is a high-purity analytical reference standard with the molecular formula C8H9BrSe and a molecular weight of 264.02 g/mol.
(2-Bromoethyl)(phenyl)selane (C8H9BrSe) contains bromine substitution, an aromatic ring system. 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.
