Chemical Structure

9,10-Dihydro-9,10[1,2]-benzenoanthracene-1,4-dione CAS 3519-82-2 chemical structure

Description

The occurrence of 9,10-Dihydro-9,10[1,2]-benzenoanthracene-1,4-dione is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

9,10-Dihydro-9,10[1,2]-benzenoanthracene-1,4-dione (CAS 3519-82-2), molecular formula C20H12O2 and molecular weight 284.31 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 9,10-Dihydro-9,10[1,2]-benzenoanthracene-1,4-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 284.31 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 9,10-Dihydro-9,10[1,2]-benzenoanthracene-1,4-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.
