Chemical Structure
Description
The occurrence of (2R,3S,4S,5R,6S)-2-(acetoxymethyl)-6-(ethylthio)tetrahydro-2H-pyran-3,4,5-triyl triacetate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2R,3S,4S,5R,6S)-2-(acetoxymethyl)-6-(ethylthio)tetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 55722-49-1), a certified reference material (molecular formula C16H24O9S, MW 392.42 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3S,4S,5R,6S)-2-(acetoxymethyl)-6-(ethylthio)tetrahydro-2H-pyran-3,4,5-triyl triacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
