Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,5-Bis(4-bromophenoxy)pentane.
1,5-Bis(4-bromophenoxy)pentane (CAS 117499-24-8), molecular formula C17H18Br2O2 and molecular weight 414.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C17H18Br2O2, 1,5-Bis(4-bromophenoxy)pentane contains a steroid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 414.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1,5-Bis(4-bromophenoxy)pentane 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.
