4,8-Diamino-1,5-dihydroxy-2,6-bis(4-methoxyphenyl)anthracene-9,10-dione CAS 79542-42-0

Description

The occurrence of 4,8-Diamino-1,5-dihydroxy-2,6-bis(4-methoxyphenyl)anthracene-9,10-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4,8-Diamino-1,5-dihydroxy-2,6-bis(4-methoxyphenyl)anthracene-9,10-dione (CAS 79542-42-0), a certified reference material (molecular formula C28H22N2O6, MW 482.48 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4,8-Diamino-1,5-dihydroxy-2,6-bis(4-methoxyphenyl)anthracene-9,10-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 482.48 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
