Chemical Structure

(-)-Syringaresinol di-O-glucoside CAS 66791-77-3 chemical structure

Description

The occurrence of (-)-Syringaresinol di-O-glucoside is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(-)-Syringaresinol di-O-glucoside (CAS 66791-77-3) is a high-purity analytical reference standard with the molecular formula C34H46O18 and a molecular weight of 742.72 g/mol.

(-)-Syringaresinol di-O-glucoside (C34H46O18) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
