Chemical Structure
Description
The occurrence of 1-Bromo-4-(trans-4-ethylcyclohexyl)benzene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-4-(trans-4-ethylcyclohexyl)benzene (CAS 91538-82-8) is a high-purity analytical reference standard with the molecular formula C14H19Br and a molecular weight of 267.20 g/mol.
The molecular framework of 1-Bromo-4-(trans-4-ethylcyclohexyl)benzene (C14H19Br) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
As a certified reference material (CRM), 1-Bromo-4-(trans-4-ethylcyclohexyl)benzene 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.
