Chemical Structure
Description
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.
Dehydroandrographolide succinate potassium sodium salt hydrate (CAS 863319-40-8(anhydrate)), molecular formula C28H34O10KNa and molecular weight 592.66 g/mol, is a CATO reference standard with documented purity and traceability.
Dehydroandrographolide succinate potassium sodium salt hydrate (C28H34O10KNa) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
