Isovitexin CAS 38953-85-4 chemical structure

Description

As a certified reference material (CRM), Isovitexin 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.

Isovitexin (CAS 38953-85-4) is a high-purity analytical reference standard with the molecular formula C21H20O10 and a molecular weight of 432.38 g/mol.

Based on its molecular formula C21H20O10, Isovitexin contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 432.38 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.
