Chemical Structure
Description
The molecular framework of 5-(Bromomethyl)-5-ethyl-2-methylheptane (C11H23Br) 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.
5-(Bromomethyl)-5-ethyl-2-methylheptane (CAS 1481858-47-2) is a high-purity analytical reference standard with the molecular formula C11H23Br and a molecular weight of 235.20 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), 5-(Bromomethyl)-5-ethyl-2-methylheptane 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.
