Chemical Structure
Description
As a certified reference material (CRM), (1-Bromopentan-2-yl)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.
(1-Bromopentan-2-yl)cyclohexane (CAS 22579-23-3), molecular formula C11H21Br and molecular weight 233.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1-Bromopentan-2-yl)cyclohexane (C11H21Br) is characterized by 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. 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.
