Chemical Structure

2,3-Dehydrosilychristin CAS 57499-41-9 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.

2,3-Dehydrosilychristin (CAS 57499-41-9), molecular formula C25H20O10 and molecular weight 480.42 g/mol, is a CATO reference standard with documented purity and traceability.

2,3-Dehydrosilychristin (C25H20O10) 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.
