Taiwanin C CAS 14944-34-4 chemical structure

Description

As a certified reference material (CRM), Taiwanin C 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.

Taiwanin C (CAS 14944-34-4), molecular formula C20H12O6 and molecular weight 348.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Taiwanin C (C20H12O6) 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 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).

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