Chemical Structure

Kaempferol Tri-O-methoxymethyl Ether CAS 143724-66-7 chemical structure

Description

The occurrence of Kaempferol Tri-O-methoxymethyl Ether is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Kaempferol Tri-O-methoxymethyl Ether (CAS 143724-66-7), molecular formula C21H22O9 and molecular weight 418.39 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Kaempferol Tri-O-methoxymethyl Ether (C21H22O9) 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).

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.

CATO manufactures Kaempferol Tri-O-methoxymethyl Ether under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
