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 4,8-Diamino-1,5-dihydroxy-2-(4-hydroxyphenyl)anthracene-9,10-dione.
CATO supplies 4,8-Diamino-1,5-dihydroxy-2-(4-hydroxyphenyl)anthracene-9,10-dione (CAS 7098-08-0), a certified reference material (molecular formula C20H14N2O5, MW 362.34 g/mol) for analytical method development and quality control.
The molecular framework of 4,8-Diamino-1,5-dihydroxy-2-(4-hydroxyphenyl)anthracene-9,10-dione (C20H14N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 4,8-Diamino-1,5-dihydroxy-2-(4-hydroxyphenyl)anthracene-9,10-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.
