Chemical Structure

Cynarin CAS 19870-46-3 chemical structure

Description

The molecular framework of Cynarin (C25H24O12) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies Cynarin (CAS 19870-46-3), a certified reference material (molecular formula C25H24O12, MW 516.45 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
