The occurrence of 5-Bromo-8-methoxy-1,2,3,4-tetrahydronaphthalene is closely related to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Bromo-8-methoxy-1,2,3,4-tetrahydronaphthalene (CAS 89682-86-0) is a high-purity analytical reference standard with the molecular formula C11H13BrO and a molecular weight of 241.12 g/mol.
The molecular framework of 5-Bromo-8-methoxy-1,2,3,4-tetrahydronaphthalene (C11H13BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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), 5-Bromo-8-methoxy-1,2,3,4-tetrahydronaphthalene 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.
