Chemical Structure

Bis(2-bromoethyl)selenium Dibromide CAS 62735-90-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 454.68 g/mol gives Bis(2-bromoethyl)selenium Dibromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bis(2-bromoethyl)selenium Dibromide (CAS 62735-90-4) is a high-purity analytical reference standard with the molecular formula C4H8Br4Se and a molecular weight of 454.68 g/mol.

Bis(2-bromoethyl)selenium Dibromide (C4H8Br4Se) contains 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.

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.
