103488-38-6 2,5-di-O-galloyl-4,6-O-(S)-hexahydroxy-diphenoyl-D-gluconic acid Punigluconin CAS 103488-38-6 chemical structure

Description

The occurrence of 103488-38-6 2,5-di-O-galloyl-4,6-O-(S)-hexahydroxy-diphenoyl-D-gluconic acid Punigluconin 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.

103488-38-6 2,5-di-O-galloyl-4,6-O-(S)-hexahydroxy-diphenoyl-D-gluconic acid Punigluconin (CAS 103488-38-6), molecular formula C34H26O23 and molecular weight 802.56 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 103488-38-6 2,5-di-O-galloyl-4,6-O-(S)-hexahydroxy-diphenoyl-D-gluconic acid Punigluconin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 802.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 103488-38-6 2,5-di-O-galloyl-4,6-O-(S)-hexahydroxy-diphenoyl-D-gluconic acid Punigluconin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
