6-Hydroxykaempferol-3,6,7-triglucoside CAS 145134-62-9 chemical structure

Description

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

6-Hydroxykaempferol-3,6,7-triglucoside (CAS 145134-62-9), molecular formula C33H40O22 and molecular weight 788.66 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-Hydroxykaempferol-3,6,7-triglucoside (C33H40O22) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 788.66 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
