Chemical Structure

6-Bromo-3,4-dihydro-3,3-dimethyl-2H-1,5-benzodioxepin CAS 1345471-22-8 chemical structure

Description

The occurrence of 6-Bromo-3,4-dihydro-3,3-dimethyl-2H-1,5-benzodioxepin is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 6-Bromo-3,4-dihydro-3,3-dimethyl-2H-1,5-benzodioxepin (CAS 1345471-22-8), a certified reference material (molecular formula C11H13BrO2, MW 257.12 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H13BrO2, 6-Bromo-3,4-dihydro-3,3-dimethyl-2H-1,5-benzodioxepin contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 257.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
