Chemical Structure

5-bromo-4-methyl-1H-indole CAS 1427412-95-0 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.

5-bromo-4-methyl-1H-indole (CAS 1427412-95-0) is a high-purity analytical reference standard with the molecular formula C9H16BrN and a molecular weight of 218.13 g/mol.

Owing to a nitrile group, bromine substitution, 5-bromo-4-methyl-1H-indole is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.13 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-bromo-4-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.
