Chemical Structure

(2R,3R,4S,5S,6R)-2-Ethoxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol CAS 3198-49-0 chemical structure

Description

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.

CATO supplies (2R,3R,4S,5S,6R)-2-Ethoxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (CAS 3198-49-0), a certified reference material (molecular formula C8H16O6, MW 208.21 g/mol) for analytical method development and quality control.

The molecular framework of (2R,3R,4S,5S,6R)-2-Ethoxy-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (C8H16O6) is characterized by a carboxylic acid group, 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
