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.

1,3:4,6-Di-O-benzylidene-D-threo-2,5-hexodiulose Hydrate 80030-25-7 [1(R),4(R)]-5-Hydroxy-1,3:4,6-bis-O-(phenylmethylene)-|A-L-sorbofuranose (CAS 80030-25-7) is a high-purity analytical reference standard with the molecular formula C20H18O6H2O and a molecular weight of 372.37 g/mol.

Structurally, 1,3:4,6-Di-O-benzylidene-D-threo-2,5-hexodiulose Hydrate 80030-25-7 [1(R),4(R)]-5-Hydroxy-1,3:4,6-bis-O-(phenylmethylene)-|A-L-sorbofuranose (C20H18O6H2O) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 372.37 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
