Chemical Structure

(2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(((3-phenylacryloyl)oxy)methyl)tetrahydro-2H-pyran-2-yl 3,4,5-trihydroxybenzoate CAS 115746-69-5 chemical structure

Description

The occurrence of (2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(((3-phenylacryloyl)oxy)methyl)tetrahydro-2H-pyran-2-yl 3,4,5-trihydroxybenzoate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(((3-phenylacryloyl)oxy)methyl)tetrahydro-2H-pyran-2-yl 3,4,5-trihydroxybenzoate (CAS 115746-69-5), molecular formula C22H22O11 and molecular weight 462.40 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2S,3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(((3-phenylacryloyl)oxy)methyl)tetrahydro-2H-pyran-2-yl 3,4,5-trihydroxybenzoate (C22H22O11) contains a flavonoid core, a hydroxyl group, an ether linkage. 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 462.40 g/mol, it falls into the moderately-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.

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.
