Chemical Structure
Description
The occurrence of 2-Fluoro-5-((8-methoxy-4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Fluoro-5-((8-methoxy-4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid (CAS 1174044-71-3), molecular formula C17H13FN2O4 and molecular weight 328.29 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-5-((8-methoxy-4-oxo-3,4-dihydrophthalazin-1-yl)methyl)benzoic acid (C17H13FN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
