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.
1-(3-Fluorophenyl)-3-(1H-indol-3-yl)urea (CAS 941879-10-3) is a high-purity analytical reference standard with the molecular formula C15H12FN3O and a molecular weight of 269.27 g/mol.
The molecular framework of 1-(3-Fluorophenyl)-3-(1H-indol-3-yl)urea (C15H12FN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-(3-Fluorophenyl)-3-(1H-indol-3-yl)urea 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.
