Chemical Structure
Description
The molecular framework of 1-(Bromomethyl)-1-(cyclopentyloxy)cyclohexane (C12H21BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-(Bromomethyl)-1-(cyclopentyloxy)cyclohexane (CAS 1249706-76-0) is a high-purity analytical reference standard with the molecular formula C12H21BrO and a molecular weight of 261.20 g/mol.
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-(Bromomethyl)-1-(cyclopentyloxy)cyclohexane 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.
