Chemical Structure
Description
The occurrence of 5-Iodo-2-methyl-1H-indole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Iodo-2-methyl-1H-indole (CAS 148322-07-0) is a high-purity analytical reference standard with the molecular formula C9H8IN and a molecular weight of 257.07 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution, 5-Iodo-2-methyl-1H-indole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.07 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.
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), 5-Iodo-2-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.
