Chemical Structure
Description
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.
(E)-6-O-(p-coumaroyl)scandoside methyl ester (cis- and trans- mixture) (CAS 83946-90-1) is a high-purity analytical reference standard with the molecular formula C26H30O13 and a molecular weight of 550.51 g/mol.
Based on its molecular formula C26H30O13, (E)-6-O-(p-coumaroyl)scandoside methyl ester (cis- and trans- mixture) 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 550.51 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
As a certified reference material (CRM), (E)-6-O-(p-coumaroyl)scandoside methyl ester (cis- and trans- mixture) 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.
