Chemical Structure

7,7-Dibromobicyclo[4.1.0]Hept-3-ene CAS 6802-78-4 chemical structure

Description

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.

CATO supplies 7,7-Dibromobicyclo[4.1.0]Hept-3-ene (CAS 6802-78-4), a certified reference material (molecular formula C7H8Br2, MW 251.95 g/mol) for analytical method development and quality control.

Structurally, 7,7-Dibromobicyclo[4.1.0]Hept-3-ene (C7H8Br2) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 251.95 g/mol, it falls into the medium-molecular-weight range. 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.
