9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acid CAS 82-49-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acid.

9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acid (CAS 82-49-5), molecular formula C14H8O5S and molecular weight 288.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H8O5S, 9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 9,10-Dioxo-9,10-dihydroanthracene-1-sulfonic acid 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.
