Chemical Structure
Description
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.
(2R,3R,4S,5R)-2,3,4,5-tetrahydroxy-6-oxohexyl 3-(4-hydroxy-3-methoxyphenyl)acrylate (CAS 252207-50-4) is a high-purity analytical reference standard with the molecular formula C16H20O9 and a molecular weight of 356.32 g/mol.
The molecular framework of (2R,3R,4S,5R)-2,3,4,5-tetrahydroxy-6-oxohexyl 3-(4-hydroxy-3-methoxyphenyl)acrylate (C16H20O9) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
As a certified reference material (CRM), (2R,3R,4S,5R)-2,3,4,5-tetrahydroxy-6-oxohexyl 3-(4-hydroxy-3-methoxyphenyl)acrylate 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.
