Puerarin Impurity 5 CAS 53681-67-7 chemical structure

Description

Puerarin Impurity 5 (CAS 53681-67-7) is a high-purity analytical reference standard with the molecular formula C27H30O14 and a molecular weight of 578.52 g/mol.

Based on its molecular formula C27H30O14, Puerarin Impurity 5 contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 578.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Puerarin Impurity 5 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.
