Chemical Structure
Description
As a certified reference material (CRM), 1-Benzyl-7-fluoro-3-(4-bromophenyl)-1H-indazole 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.
CATO supplies 1-Benzyl-7-fluoro-3-(4-bromophenyl)-1H-indazole (CAS 1809161-44-1), a certified reference material (molecular formula C20H14BrFN2, MW 381.24 g/mol) for analytical method development and quality control.
Structurally, 1-Benzyl-7-fluoro-3-(4-bromophenyl)-1H-indazole (C20H14BrFN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 381.24 g/mol, it falls into the moderately-high-molecular-weight range. 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.
