Chemical Structure
Description
As a certified reference material (CRM), 5-(3-Bromo-5-fluorophenoxy)pentanenitrile 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.
5-(3-Bromo-5-fluorophenoxy)pentanenitrile (CAS 1443335-40-7), molecular formula C11H11BrFNO and molecular weight 272.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(3-Bromo-5-fluorophenoxy)pentanenitrile (C11H11BrFNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/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.
