Chemical Structure

Bisdemethoxycurcumin CAS 24939-16-0 chemical structure

Description

Bisdemethoxycurcumin (CAS 24939-16-0) is a high-purity analytical reference standard with the molecular formula C19H16O4 and a molecular weight of 308.33 g/mol.

Bisdemethoxycurcumin (C19H16O4) contains a flavonoid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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.
