Chemical Structure

luteolin-7-O-gentiobiside CAS 70855-41-3 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.

luteolin-7-O-gentiobiside (CAS 70855-41-3) is a high-purity analytical reference standard with the molecular formula C27H30O16 and a molecular weight of 610.52 g/mol.

luteolin-7-O-gentiobiside (C27H30O16) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), luteolin-7-O-gentiobiside 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.
