Chemical Structure

2,5-Dibromohexanedioyl Dichloride CAS 29548-86-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2,5-Dibromohexanedioyl Dichloride (CAS 29548-86-5), a certified reference material (molecular formula C6H6Br2Cl2O2, MW 340.82 g/mol) for analytical method development and quality control.

Structurally, 2,5-Dibromohexanedioyl Dichloride (C6H6Br2Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 340.82 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
