Chemical Structure

1,8-Bis(2-bromoethoxy)anthracene-9,10-dione CAS 69595-68-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 454.11 g/mol gives 1,8-Bis(2-bromoethoxy)anthracene-9,10-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1,8-Bis(2-bromoethoxy)anthracene-9,10-dione (CAS 69595-68-2), a certified reference material (molecular formula C18H14Br2O4, MW 454.11 g/mol) for analytical method development and quality control.

The molecular framework of 1,8-Bis(2-bromoethoxy)anthracene-9,10-dione (C18H14Br2O4) is characterized by a flavonoid core, 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. 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.

As a certified reference material (CRM), 1,8-Bis(2-bromoethoxy)anthracene-9,10-dione 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.
