As a certified reference material (CRM), (2R,3R,4R,5R,6S)-3-(Allyloxy)-2,5-bis(benzyloxy)-6-methyltetrahydro-2H-pyran-4-ol 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.
(2R,3R,4R,5R,6S)-3-(Allyloxy)-2,5-bis(benzyloxy)-6-methyltetrahydro-2H-pyran-4-ol (CAS 69558-10-7) is a high-purity analytical reference standard with the molecular formula C23H28O5 and a molecular weight of 384.47 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (2R,3R,4R,5R,6S)-3-(Allyloxy)-2,5-bis(benzyloxy)-6-methyltetrahydro-2H-pyran-4-ol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.47 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.
