Chemical Structure

Myricetin 3-O-(3''-galloylrhamnopyranoside) CAS 143202-36-2 chemical structure

Description

The occurrence of Myricetin 3-O-(3''-galloylrhamnopyranoside) is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Myricetin 3-O-(3''-galloylrhamnopyranoside) (CAS 143202-36-2), molecular formula C28H24O16 and molecular weight 616.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, Myricetin 3-O-(3''-galloylrhamnopyranoside) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 616.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

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.
