Chemical Structure

16,17-Dihydroxyanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione CAS 128-59-6 chemical structure

Description

The occurrence of 16,17-Dihydroxyanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 16,17-Dihydroxyanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione (CAS 128-59-6), a certified reference material (molecular formula C34H16O4, MW 488.49 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 16,17-Dihydroxyanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 488.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 16,17-Dihydroxyanthra[9,1,2-cde]benzo[rst]pentaphene-5,10-dione 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.
