Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 424.49 g/mol gives Tetramethylcurcumin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetramethylcurcumin (CAS 52328-97-9) is a high-purity analytical reference standard with the molecular formula C25H28O6 and a molecular weight of 424.49 g/mol.
The molecular framework of Tetramethylcurcumin (C25H28O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
