Chemical Structure

4-bromo-1-methyl-1H-indole CAS 590417-55-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-bromo-1-methyl-1H-indole.

4-bromo-1-methyl-1H-indole (CAS 590417-55-3) 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, 4-bromo-1-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.

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.

CATO manufactures 4-bromo-1-methyl-1H-indole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
