Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Fluoro-3-methyl-1H-indole (CAS 392-13-2) is a high-purity analytical reference standard with the molecular formula C9H8FN and a molecular weight of 149.16 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 5-Fluoro-3-methyl-1H-indole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-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.
