Chemical Structure
Description
CATO supplies 1-t-Butyl-6-fluorobenzoimidazole (CAS 1187385-71-2), a certified reference material (molecular formula C11H13FN2, MW 192.23 g/mol) for analytical method development and quality control.
The molecular framework of 1-t-Butyl-6-fluorobenzoimidazole (C11H13FN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
As a certified reference material (CRM), 1-t-Butyl-6-fluorobenzoimidazole 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.
