Chemical Structure
Description
The occurrence of 1,2,3,6-Tetragalloylglucose 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.
1,2,3,6-Tetragalloylglucose (CAS 79886-50-3), molecular formula C34H28O22 and molecular weight 788.57 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, 1,2,3,6-Tetragalloylglucose is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 788.57 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), 1,2,3,6-Tetragalloylglucose 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.
