Chemical Structure

Luteolin-7-O-glucuronide CAS 29741-10-4 chemical structure

Description

Owing to a flavonoid core, a hydroxyl group, an ether linkage, Luteolin-7-O-glucuronide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 462.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Luteolin-7-O-glucuronide (CAS 29741-10-4), molecular formula C21H18O12 and molecular weight 462.36 g/mol, is a CATO reference standard with documented purity and traceability.

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), Luteolin-7-O-glucuronide 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.
