Chemical Structure

3-Bromo-2-methyl-1-(4-methylphenyl)-4,5,6,7-tetrahydro-1H-indol-4-one CAS 327082-74-6 chemical structure

Description

3-Bromo-2-methyl-1-(4-methylphenyl)-4,5,6,7-tetrahydro-1H-indol-4-one (CAS 327082-74-6), molecular formula C16H16BrNO and molecular weight 318.21 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Bromo-2-methyl-1-(4-methylphenyl)-4,5,6,7-tetrahydro-1H-indol-4-one (C16H16BrNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 3-Bromo-2-methyl-1-(4-methylphenyl)-4,5,6,7-tetrahydro-1H-indol-4-one 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.
