Chemical Structure

Dihydroartemisinin O-β-D-glucuronide CAS 198976-06-6 chemical structure

Description

The occurrence of Dihydroartemisinin O-β-D-glucuronide is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dihydroartemisinin O-β-D-glucuronide (CAS 198976-06-6), molecular formula C21H32O11 and molecular weight 460.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dihydroartemisinin O-β-D-glucuronide (C21H32O11) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 460.47 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.
