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 (2R,3S,4S,5R,6R)-2-(hydroxymethyl)-6-(naphthalen-2-yloxy)tetrahydro-2H-pyran-3,4,5-triol.
CATO supplies (2R,3S,4S,5R,6R)-2-(hydroxymethyl)-6-(naphthalen-2-yloxy)tetrahydro-2H-pyran-3,4,5-triol (CAS 25320-79-0), a certified reference material (molecular formula C16H18O6, MW 306.31 g/mol) for analytical method development and quality control.
(2R,3S,4S,5R,6R)-2-(hydroxymethyl)-6-(naphthalen-2-yloxy)tetrahydro-2H-pyran-3,4,5-triol (C16H18O6) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
