Chemical Structure

4-fluoro-3-methyl-1H-indole CAS 1011484-22-2 chemical structure

Description

As a certified reference material (CRM), 4-fluoro-3-methyl-1H-indole 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.

4-fluoro-3-methyl-1H-indole (CAS 1011484-22-2) is a high-purity analytical reference standard with the molecular formula C9H16FN and a molecular weight of 157.23 g/mol.

The molecular framework of 4-fluoro-3-methyl-1H-indole (C9H16FN) is characterized by a nitrile group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
