Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies (2R,4aR,6S,7R,8R,8aS)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-6,7,8-triol (CAS 113566-67-9), a certified reference material (molecular formula C13H16O6, MW 268.26 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,4aR,6S,7R,8R,8aS)-2-phenylhexahydropyrano[3,2-d][1,3]dioxine-6,7,8-triol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
