Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 2-(4-Bromophenyl)cyclohexanone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.14 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.
2-(4-Bromophenyl)cyclohexanone (CAS 91720-92-2) is a high-purity analytical reference standard with the molecular formula C12H13BrO and a molecular weight of 253.14 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-Bromophenyl)cyclohexanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
