Chemical Structure

(2R,3R,4S,5R,6R)-4-(allyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-2,3,5-triol CAS 77388-91-1 chemical structure

Description

(2R,3R,4S,5R,6R)-4-(allyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-2,3,5-triol (CAS 77388-91-1), molecular formula C9H16O6 and molecular weight 220.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H16O6, (2R,3R,4S,5R,6R)-4-(allyloxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-2,3,5-triol contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 220.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

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.
