Chemical Structure
Description
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.
CATO supplies 1-(3-Bromo-2-fluorophenyl)cyclopentane-1-carbonitrile (CAS 1881330-55-7), a certified reference material (molecular formula C12H11BrFN, MW 268.12 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3-Bromo-2-fluorophenyl)cyclopentane-1-carbonitrile (C12H11BrFN) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
As a certified reference material (CRM), 1-(3-Bromo-2-fluorophenyl)cyclopentane-1-carbonitrile 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.
