Description

As a certified reference material (CRM), 5-Hydroxy-6-(3-hydroxy-4-methoxyphenethoxy)-2-(hydroxymethyl)-4-((3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl 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.

5-Hydroxy-6-(3-hydroxy-4-methoxyphenethoxy)-2-(hydroxymethyl)-4-((3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl 3-(4-hydroxy-3-methoxyphenyl)acrylate (CAS 165338-27-2) is a high-purity analytical reference standard with the molecular formula C31H40O16 and a molecular weight of 668.64 g/mol.

Structurally, 5-Hydroxy-6-(3-hydroxy-4-methoxyphenethoxy)-2-(hydroxymethyl)-4-((3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-3-yl 3-(4-hydroxy-3-methoxyphenyl)acrylate (C31H40O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 668.64 g/mol, it falls into the high-molecular-weight range. 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.
