Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.15 g/mol gives (1R,3R)-3-(4-Bromophenyl)cyclohexane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (1R,3R)-3-(4-Bromophenyl)cyclohexane (CAS 1389859-88-4), a certified reference material (molecular formula C12H15Br, MW 239.15 g/mol) for analytical method development and quality control.
The molecular framework of (1R,3R)-3-(4-Bromophenyl)cyclohexane (C12H15Br) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
