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 8-Acetyl-7,8,9,10-tetrahydro-6,11-dihydroxy-5,12-naphthacenedione.
CATO supplies 8-Acetyl-7,8,9,10-tetrahydro-6,11-dihydroxy-5,12-naphthacenedione (CAS 67122-26-3), a certified reference material (molecular formula C20H16O5, MW 336.34 g/mol) for analytical method development and quality control.
The molecular framework of 8-Acetyl-7,8,9,10-tetrahydro-6,11-dihydroxy-5,12-naphthacenedione (C20H16O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 8-Acetyl-7,8,9,10-tetrahydro-6,11-dihydroxy-5,12-naphthacenedione 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.
