Chemical Structure

Ginsenoside Rg4 CAS 126223-28-7 chemical structure

Description

Ginsenoside Rg4 (CAS 126223-28-7), molecular formula C42H70O12 and molecular weight 767.00 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ginsenoside Rg4 (C42H70O12) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 767.00 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ginsenoside Rg4 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.
