Chemical Structure
Description
The occurrence of 4-(4-Fluorophenyl)-7,8-dimethoxy-2-naphthoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(4-Fluorophenyl)-7,8-dimethoxy-2-naphthoic acid (CAS 1263209-44-4), molecular formula C19H15FO4 and molecular weight 326.32 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H15FO4, 4-(4-Fluorophenyl)-7,8-dimethoxy-2-naphthoic acid contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
