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 2,6,7-Trihydroxy-9-phenyl-3h-xanthen-3-one.
CATO supplies 2,6,7-Trihydroxy-9-phenyl-3h-xanthen-3-one (CAS 975-17-7), a certified reference material (molecular formula C19H12O5, MW 320.30 g/mol) for analytical method development and quality control.
The molecular framework of 2,6,7-Trihydroxy-9-phenyl-3h-xanthen-3-one (C19H12O5) 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.
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.
