Chemical Structure

3,5-Dibromobenzyl Bromide CAS 56908-88-4 chemical structure

Description

3,5-Dibromobenzyl Bromide (CAS 56908-88-4) is a high-purity analytical reference standard with the molecular formula C7H5Br3 and a molecular weight of 328.83 g/mol.

Structurally, 3,5-Dibromobenzyl Bromide (C7H5Br3) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 328.83 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
