Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 252.26 g/mol gives 3-Methoxyflavone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methoxyflavone (CAS 7245-02-5), molecular formula C16H12O3 and molecular weight 252.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Methoxyflavone (C16H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 252.26 g/mol, it falls into the medium-molecular-weight range. 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.
