Description

(2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-(((2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-(4-nitrophenoxy)tetrahydro-2H-pyran-2-yl)methoxy)tetrahydro-2H-pyran-3,4,5-triol (CAS 335193-88-9) is a high-purity analytical reference standard with the molecular formula C18H25NO13 and a molecular weight of 463.39 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-(((2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-(4-nitrophenoxy)tetrahydro-2H-pyran-2-yl)methoxy)tetrahydro-2H-pyran-3,4,5-triol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 463.39 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.

As a certified reference material (CRM), (2R,3S,4S,5R,6S)-2-(hydroxymethyl)-6-(((2R,3S,4S,5R,6S)-3,4,5-trihydroxy-6-(4-nitrophenoxy)tetrahydro-2H-pyran-2-yl)methoxy)tetrahydro-2H-pyran-3,4,5-triol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
