Chemical Structure

2,3-Dibromo-5,6,7,8-tetrachloro-1,4-dihydroxyanthracene-9,10-dione CAS 99562-96-6 chemical structure

Description

The occurrence of 2,3-Dibromo-5,6,7,8-tetrachloro-1,4-dihydroxyanthracene-9,10-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,3-Dibromo-5,6,7,8-tetrachloro-1,4-dihydroxyanthracene-9,10-dione (CAS 99562-96-6) is a high-purity analytical reference standard with the molecular formula C14H2Br2Cl4O4 and a molecular weight of 535.78 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, a polycyclic aromatic system, 2,3-Dibromo-5,6,7,8-tetrachloro-1,4-dihydroxyanthracene-9,10-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 535.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2,3-Dibromo-5,6,7,8-tetrachloro-1,4-dihydroxyanthracene-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.
