Chemical Structure

3-Bromocyclohex-2-en-1-one CAS 56671-81-9 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.

3-Bromocyclohex-2-en-1-one (CAS 56671-81-9) is a high-purity analytical reference standard with the molecular formula C6H7BrO and a molecular weight of 175.02 g/mol.

Owing to a hydroxyl group, an ether linkage, bromine substitution, 3-Bromocyclohex-2-en-1-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
