Malvidin 3,5-diglucoside CAS 16727-30-3

Description

Compared with other compounds in its class, the molecular weight of 655.58 g/mol gives Malvidin 3,5-diglucoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Malvidin 3,5-diglucoside (CAS 16727-30-3), molecular formula C29H35O17 and molecular weight 655.58 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Malvidin 3,5-diglucoside (C29H35O17) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 655.58 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.

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.
