Chemical Structure
Description
(2R,3S,4S,5R,6S)-2-(Hydroxymethyl)-6-(2,4,6-trimethoxyphenoxy)tetrahydro-2H-pyran-3,4,5-triol 125288-25-7 ST24034033 (CAS 125288-25-7), molecular formula C15H22O9 and molecular weight 346.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, (2R,3S,4S,5R,6S)-2-(Hydroxymethyl)-6-(2,4,6-trimethoxyphenoxy)tetrahydro-2H-pyran-3,4,5-triol 125288-25-7 ST24034033 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.33 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).
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.
