Chemical Structure
Description
The occurrence of Kaempferol-3-Glucuronide 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.
CATO supplies Kaempferol-3-Glucuronide (CAS 22688-78-4), a certified reference material (molecular formula C21H18O12, MW 462.36 g/mol) for analytical method development and quality control.
Kaempferol-3-Glucuronide (C21H18O12) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Kaempferol-3-Glucuronide 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.
