Chemical Structure
Description
5-Bromo-1-(4-methylbenzyl)-1H-indole (CAS 481630-73-3) is a high-purity analytical reference standard with the molecular formula C16H14BrN and a molecular weight of 300.19 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 5-Bromo-1-(4-methylbenzyl)-1H-indole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 5-Bromo-1-(4-methylbenzyl)-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.
